Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Fig. 1 is a flowchart of a method for controlling pressure of a compressor station room according to an embodiment of the present disclosure. The method is suitable for the condition that the compressor station room outputs the gas to the user terminal. The method can be executed by a compressor station room pressure control device, and the compressor station room pressure control device can be realized in a software and/or hardware mode. As shown in fig. 1, the method comprises the steps of:
and S110, monitoring the terminal pressure in real time.
In the embodiment of the disclosure, the terminal pressure is the pressure at the output end of the compressor station room. In one example, the terminal is provided with a pressure sensor, the pressure sensor is connected to the control system through a fiber communication or wireless communication module, and field real-time pressure data (namely, terminal pressure) is transmitted to the control system, so that real-time monitoring on the terminal pressure is realized.
And S120, controlling the running state of the compressor in the compressor station room based on the terminal pressure, the preset pressure lower limit value and the preset pressure upper limit value, so as to adjust the terminal pressure to a closed interval between the preset pressure lower limit value and the preset pressure upper limit value.
The lower preset pressure limit value and the upper preset pressure limit value are used for limiting the actual pressure value required by the user. The operating state of the compressor may include start-up and unloading (shutdown) of the compressor. Therefore, the control system compares the terminal pressure with a preset pressure lower limit value and a preset pressure upper limit value based on the terminal pressure fed back by the output end of the compressor station house in real time, and adjusts the terminal pressure to be between the preset pressure lower limit value and the preset pressure upper limit value by controlling the starting and the unloading of the compressor according to the comparison result, so that the pressure output by the compressor station house meets the actual required pressure value of a user. It should be noted that the preset pressure lower limit value and the preset pressure upper limit value referred to in the present disclosure may vary with the actual pressure value demanded by the user.
In summary, according to the method for controlling the pressure of the compressor station room provided by the embodiment of the disclosure, the terminal pressure is monitored in real time, and the operating state of the compressor in the compressor station room is dynamically controlled according to the real-time terminal pressure, the lower limit value of the preset pressure and the upper limit value of the preset pressure, so that the terminal pressure is between the lower limit value of the preset pressure and the upper limit value of the preset pressure, and the lower limit value of the preset pressure and the upper limit value of the preset pressure are used for limiting the actual required pressure value of the user.
Based on the above technical solution, in some embodiments, the method for controlling the operation state of the compressor in the compressor station based on the terminal pressure, the preset pressure lower limit value and the preset pressure upper limit value includes the following steps:
and S121, judging whether the terminal pressure is greater than or equal to a preset pressure lower limit value or not.
And S122, when the terminal pressure is smaller than the lower limit value of the preset pressure, starting the compressors in sequence according to a preset starting sequence, and stopping starting the compressors until the terminal pressure is larger than or equal to the lower limit value of the preset pressure.
When the terminal pressure is smaller than the preset pressure lower limit value, it indicates that the currently started compressor (including the initial condition) cannot meet the actual demand pressure of the user, and therefore the number of started compressors needs to be increased. In this embodiment, start the empty air pressure according to a preset start order in proper order, can make terminal pressure reach preset pressure lower limit value comparatively steadily, can prevent the pressure overload of compressor station room output to a certain extent. Specifically, a priority is set for each compressor in advance, and the compressors with lower priorities are set to start preferentially, that is, the compressors are started sequentially from low to high in priority. For example, the priority number may be a natural number 0,1,2. Illustratively, when the terminal pressure is smaller than the preset pressure lower limit value, the compressor with the priority number of 0 is initially started by default, and 1 is added to the priority number to determine the compressor to be started next time; and after the compressor with the priority number of 0 is started, returning to S121, judging whether the terminal pressure is greater than or equal to the lower limit value of the preset pressure again, if the terminal pressure is still less than the lower limit value of the preset pressure, continuing to start the compressor with the priority number of 1, adding 1 to the priority number, and returning to S121. And circulating in the above way, and stopping starting the compressor until the terminal pressure is greater than or equal to the lower limit value of the preset pressure. In one embodiment, the preset starting sequence is a sequence from small to large of the priority numbers of the compressors, wherein the priority number of the screw machine in the compressor is smaller than that of the centrifugal compressor in the compressor, and the longer the starting time of the compressor after the compressor station room is started last time is, the larger the priority number of the compressor when the compressor station room is started next time is, wherein the priority numbers of the compressors with the same starting time are set by default. It can be understood that if the compressor station is initially started when the compressor station is started next time, the starting time of the compressors after the compressor station is started last time is considered to be 0, the priority number of all the compressors is set by default, and in the case of a screw machine, the priority number of the screw machine is smaller than that of the centrifugal compressor. For the case that the compressor only comprises a plurality of centrifugal compressors, the screw machine does not need to be considered, and the priority number of the compressor when the compressor station room is started next time is determined according to the longer starting time of the compressor after the compressor station room is started last time. And for the condition that the compressor comprises at least one screw machine and at least one centrifugal compressor, the priority number of the screw machine when the compressor station room is started next time can be determined according to the longer starting time of the screw machine after the compressor station room is started last time, and the priority number of the centrifugal compressor when the compressor station room is started next time can be determined according to the sequence of the priority numbers after the priority number of the screw machine is determined and the longer starting time of the centrifugal compressor after the compressor station room is started last time. In this scheme, consider that terminal pressure is positively correlated with the flow of compressor, the flow of compressor is big more promptly, and terminal pressure is also big more, consequently, when user's actual demand pressure is less, preferentially open the great compressor of flow adjustable range, can export less flow for terminal pressure just satisfies user's actual demand pressure, avoids the flow surplus, further prevents the pressure overload of compressor station room output. The flow adjustable range of the screw machine is larger and is 10% -100%, the flow adjustable range of the centrifugal compressor is smaller and is 70% -100%, therefore, the priority number of the screw machine is set to be smaller, the priority number of the centrifugal compressor is larger, and the screw machine is guaranteed to be started preferentially. In addition, the longer the starting time of the compressor after the compressor station room is started last time, the larger the priority number of the compressor when the compressor station room is started next time, so that the compressor with the shorter starting time last time can be started next time, the starting time of each compressor is balanced, and the service life of the compressor station room is prolonged as a whole.
It should be noted that there may be some cases where the start-up of the compressor fails due to a failure of the compressor or the like. Considering that the condition of the failed start of the compressor does not influence the terminal pressure, namely the terminal pressure after the failed start of the compressor is the same as the terminal pressure before the start of the compressor. Therefore, in order to improve the efficiency, whether the terminal pressure is greater than or equal to the lower limit value of the preset pressure can not be judged again after the starting of the compressor fails, but the next compressor is started continuously directly based on the preset starting sequence, and whether the terminal pressure is greater than or equal to the lower limit value of the preset pressure can be judged continuously only after the compressor is started successfully. In addition, the device can send out an alarm signal when the compressor fails to start, thereby reminding maintenance personnel to maintain the compressor.
And S123, when the terminal pressure is greater than or equal to the lower limit value of the preset pressure, judging whether the terminal pressure is less than or equal to the upper limit value of the preset pressure.
After the terminal pressure is determined to be greater than or equal to the lower limit value of the preset pressure, in order to ensure that the terminal pressure meets the actual pressure value required by a user and the requirement that the terminal pressure is constant, whether the terminal pressure is less than or equal to the upper limit value of the preset pressure needs to be further judged, and the compressor station room can be in constant-pressure operation only when the terminal pressure is less than or equal to the upper limit value of the preset pressure at the same time.
And S124, when the terminal pressure is greater than the preset pressure upper limit value, responding to the fact that the total load rate of the current joint control equipment corresponding to the compressor entering the joint control operation is smaller than the load rate threshold value, sequentially unloading the compressors according to a preset unloading sequence until the terminal pressure is in a closed interval between the preset pressure lower limit value and the preset pressure upper limit value, stopping unloading the compressors, or stopping unloading the compressors and reloading the currently unloaded compressors when the terminal pressure is smaller than the preset pressure lower limit value.
The joint control equipment comprises a compressor and loads thereof (the loads can comprise a dryer, a water cooler and the like), when the compressor is started, the dryer and the water cooler which are related to the compressor run in a linkage mode, and the compressor which runs in the joint control mode is the compressor. In addition, the total load rate of the current joint control equipment is smaller than the load rate threshold value, which shows that the current load of the whole compressor station house is too light, so that the energy consumption is reduced, the waste is avoided, and the started compressor can be properly unloaded. Alternatively, the load factor threshold may be 76%, 78%, 80%, 82%, 84%, or the like, and may be set according to actual situations. In this embodiment, when the terminal pressure is greater than the preset pressure upper limit value, the total load rate of the current joint control device is obtained, the total load rate is compared with a load rate threshold value, and when the total load rate is less than the load rate threshold value, the compressors are sequentially unloaded according to a preset unloading sequence. Specifically, real-time data of a compressor entering joint control operation is obtained; calculating the current total real-time power and the total rated power based on the real-time data; and obtaining the total load rate of the current joint control equipment based on the ratio of the total real-time power to the total rated power. When the total load rate is greater than or equal to the load rate threshold, the process returns to S121 and S121 to S124 may be executed again.
In this embodiment, the compressors are unloaded sequentially according to a preset unloading sequence, specifically, the load of the compressors is unloaded while the compressors are unloaded. The compressors are unloaded one by one according to the preset unloading sequence, so that the whole compressor station room cannot cause large fluctuation due to unloading of the loads, and the power stability of the whole compressor station room is ensured to a certain extent. In a preferred embodiment, the predetermined unloading sequence is a sequence of the rated power of the compressor from small to large. Specifically, the rated power of the running compressor is counted first, and the compressor with the minimum rated power is matched, so that the compressor and the load of the compressor are unloaded. After the compressor is unloaded, the terminal pressure is inevitably reduced, and in order to avoid excessive reduction of the terminal pressure, after the compressor is unloaded, whether the terminal pressure is greater than or equal to the lower limit value of the preset pressure is judged, when the terminal pressure is greater than or equal to the lower limit value of the preset pressure, the step returns to the step S123, the step S123 and the step S124 are executed again, if the terminal pressure is still greater than the upper limit value of the preset pressure at the moment and the total load rate of the current joint control equipment is less than the load rate threshold value, the compressor with the second-smallest rated power is matched, and the compressor and the load thereof are unloaded. And then, judging whether the terminal pressure is greater than or equal to a preset pressure lower limit value, returning to S123 and re-executing S123 and S124 when the terminal pressure is greater than or equal to the preset pressure lower limit value. And stopping unloading the compressor until the terminal pressure is in the closed interval between the lower preset pressure limit value and the upper preset pressure limit value, wherein the compressor station room is in constant-pressure operation, or stopping unloading the compressor and reloading the compressor unloaded at the time when the terminal pressure is smaller than the lower preset pressure limit value. In this embodiment, the preset unloading sequence is set as the sequence from small to large of the rated power of the compressor, so that the power stability of the whole compressor station can be further ensured, and large fluctuation caused by unloading of the load is avoided. It should be noted that, after the compressor is unloaded, if the holding time when the terminal pressure is greater than or equal to the preset pressure lower limit value is greater than 30 minutes, the unloaded compressor automatically enters the shutdown process, and returns to S123.
In the above embodiment, when the total load rate of the current joint control device is smaller than the load rate threshold, the compressors may be sequentially unloaded according to the preset unloading sequence after a preset time period. Therefore, when the total load rate of the current joint control equipment is smaller than the load rate threshold value, the procedure of unloading the compressor is executed after a preset time period, and the compressor can be automatically unloaded in the stable operation without large air pressure fluctuation. Optionally, the preset time period is 30 minutes.
And S125, if the compressor is stopped to be unloaded and the compressor unloaded at the time is reloaded, when the terminal pressure is smaller than the lower limit value of the preset pressure or larger than the upper limit value of the preset pressure, returning to execute the steps until the terminal pressure is in a closed interval between the lower limit value of the preset pressure and the upper limit value of the preset pressure.
In this embodiment, if the unloading of the compressor is stopped and the currently unloaded compressor is reloaded, when the terminal pressure is less than the preset pressure lower limit value or greater than the preset pressure upper limit value, the process returns to S121, and S121 to S125 are executed again until the terminal pressure is greater than or equal to the preset pressure lower limit value and less than or equal to the preset pressure upper limit value, and at this time, the compressor station is in constant-pressure operation.

As shown in fig. 2, in one specific example, the compressor station room pressure control method includes: after the control system is initialized, judging whether the terminal pressure is greater than or equal to a preset pressure lower limit value; when the terminal pressure is smaller than the lower limit value of the preset pressure, starting the compressors in sequence according to the preset starting sequence, judging whether the compressors are started successfully or not after the compressors are started each time, returning to continuously judge whether the terminal pressure is larger than or equal to the lower limit value of the pressure or not if the compressors are started successfully, and directly starting the next compressor according to the preset starting sequence if the compressors are not started successfully; when the terminal pressure is greater than or equal to the preset pressure lower limit value, judging whether the terminal pressure is less than or equal to the preset pressure upper limit value, and when the terminal pressure is greater than the preset pressure upper limit value, judging whether the total load rate e of the current joint control equipment is less than a load rate threshold value; if e is less than the load rate threshold, unloading the compressors in sequence according to a preset unloading sequence, judging whether the terminal pressure is greater than or equal to a preset pressure lower limit value after unloading the compressors each time, returning to judge whether the terminal pressure is less than or equal to the preset pressure upper limit value when the terminal pressure is greater than or equal to the preset pressure lower limit value, loading the compressor unloaded each time when the terminal pressure is less than the preset pressure lower limit value, returning to judge whether the terminal pressure is greater than or equal to the preset pressure lower limit value after system initialization, and returning to judge whether the terminal pressure is greater than or equal to the preset pressure lower limit value after system initialization if e is greater than or equal to the load rate threshold; and when the terminal pressure is less than or equal to the preset pressure upper limit value, determining that the compressor station room is in constant-pressure operation.
