Fig. 1 is a flowchart of a first embodiment of a method for controlling a test state of a wind turbine generator system according to the present invention, where an execution main body of the method for controlling a test state of a wind turbine generator system is a control device of a test state of a wind turbine generator system, and the control device of a test state of a wind turbine generator system is integrated in a main controller, a variable current controller, and/or a variable pitch controller of the wind turbine generator system. The control device of the test state of the wind generating set is communicated with the test client of the wind generating set through a tested main body of the wind generating set. As shown in fig. 1, the method for controlling the test status of the wind turbine generator system provided by this embodiment includes the following steps.
Step 101, if the wind generating set starts a test, whether heartbeat information sent by a test client of the wind generating set is received or not is judged.
The test client of the wind generating set is mainly a software or hardware product developed aiming at the test of the wind generating set and used for completing a specific test purpose.
Specifically, in this embodiment, first, after the control device of the test state of the wind generating set receives the test request sent by the test client through the tested main body of the wind generating set, the control device of the test state of the wind generating set controls the wind generating set to start the test according to the test request, and sends the feedback information for determining to enter the test state to the test client through the tested main body of the wind generating set. And after the control device of the test state of the wind generating set controls the wind generating set to start the test, judging whether the heartbeat information sent by the test client side is received.
In this embodiment, the type of the heartbeat information is not limited. Such as may be a pulsed signal. The heartbeat information is set by a test client and a control device of the test state of the wind generating set in advance through a proprietary protocol.
And step 102, if heartbeat information sent by a test client of the wind generating set is received, the test state is kept.
And 103, if the heartbeat information sent by the test client of the wind generating set is not received, exiting the test state.
This embodiment will be described with reference to step 102 and step 103. Specifically, the heartbeat information is used for judging whether to control the wind generating set to keep a test state. If the heartbeat information sent by the test client is received, the test client is not interfered by the uncertain factors, the wind generating set is continuously controlled to keep the test state, and if the heartbeat information sent by the test client is not received, the test client is interfered by the uncertain factors or the control device of the test state of the wind generating set receives a test termination instruction, the test of the wind generating set is required to be terminated, and the wind generating set is controlled to exit the test state. Therefore, in this embodiment, the control device for the test state of the wind generating set uses whether the heartbeat information is received as a basis for controlling the wind generating set to exit the test state.
Wherein, the uncertain factor can be: the test client crashes, the test client suddenly cuts power, and the like.
According to the control method for the test state of the wind generating set, whether heartbeat information sent by a test client of the wind generating set is received or not is judged if the wind generating set starts a test; if heartbeat information sent by a test client of the wind generating set is received, the test state is kept; and if the heartbeat information sent by the test client of the wind generating set is not received, exiting the test state. Because whether heartbeat information is received or not is used as a basis for controlling the test state of the wind generating set, the test client can be interfered by uncertain factors, and the control device of the test state of the wind generating set can still exit the test state when the test termination instruction is not received, so that the influence on the normal power generation and monitoring of the wind generating set is avoided, and the service life of the wind generating set is prolonged.
Fig. 2 is a flowchart of a second method for controlling a test state of a wind turbine generator system according to an embodiment of the present invention, and as shown in fig. 2, the method for controlling a test state of a wind turbine generator system according to this embodiment is further detailed in step 103 on the basis of the first method for controlling a test state of a wind turbine generator system according to this embodiment, and then the method for controlling a test state of a wind turbine generator system according to this embodiment includes the following steps.
Further, in this embodiment, the heartbeat information is a pulse signal. And/or in this embodiment, the heartbeat information is heartbeat information periodically sent by the test client.
And step 204, the tested main body of the wind generating set exits from the testing state.
Further, the present embodiment is explained with reference to step 201 to step 204. In this embodiment, a test client of the wind turbine generator system periodically sends heartbeat information as an example for explanation. If the wind generating set starts the test, the test client periodically sends heartbeat information, and when the communication between the test client and the control device of the test state of the wind generating set is smooth and no uncertain factor interference exists, the control device of the test state of the wind generating set periodically receives the heartbeat information, so that the phenomenon of heartbeat information loss is avoided. If the heartbeat information sent periodically is received, the testing client needs to continue testing the wind generating set, and the wind generating set is controlled to keep in a testing state. If communication between the test client and the control device for testing the test state of the wind generating set is not smooth without interference of uncertain factors and network delay exists, the phenomenon of heartbeat information loss occurs. At this moment, the control device of the wind generating set in the test state can not receive the heartbeat information periodically any more, and the phenomenon that the next heartbeat information is received at intervals occurs, in order to avoid accidentally quitting the test state, whether the time when the heartbeat information is not received reaches the preset time is judged, if the time when the heartbeat information is not received does not reach the preset time, the wind generating set is continuously controlled to keep the test state, and if the time when the heartbeat information is not received reaches the preset time, the wind generating set is controlled to quit the test state, if the time when the heartbeat information is not received does not reach the preset time, the heartbeat information is not received due to interference of uncertain factors, and the wind generating set is judged to be in the test state.
The preset time is greater than the period of sending the heartbeat information. If the period of sending the heartbeat information is 1 second, the preset time may be 15 seconds. The preset time may also be other suitable values, which is not limited in this embodiment.
It should be noted that, in the embodiment, in the process of receiving the heartbeat information, the test instruction sent by the test client is also received, so as to collect test data according to the test instruction, and send a test response to the test client. The heartbeat information may be sent alone or together with the test instruction, which is not limited in this embodiment.
According to the control method for the test state of the wind generating set provided by the embodiment, whether heartbeat information sent by the test client of the wind generating set is received or not is judged if the wind generating set starts the test, and if the heartbeat information is received, the tested main body of the wind generating set keeps the test state. Otherwise, judging whether the time for not receiving the heartbeat information reaches the preset time, if so, exiting the test state of the tested main body of the wind generating set, and if not, keeping the tested main body of the wind generating set in the test state. The test state can still be exited when the test termination instruction is not received under the interference of uncertain factors, and the phenomenon that the test state is exited accidentally due to network delay is avoided.
Fig. 3 is a flowchart of a third embodiment of the control method for the test state of the wind turbine generator system, and as shown in fig. 3, an execution main body of the control method for the test state of the wind turbine generator system provided by this embodiment is a test client of the wind turbine generator system, and the test client communicates with a control device for the test state of the wind turbine generator system through a tested main body of the wind turbine generator system. The control method for the test state of the wind generating set provided by the embodiment comprises the following steps.
The tested main body of the wind generating set can be a main controller, a variable flow controller and/or a variable pitch controller of the wind generating set.
Specifically, in this embodiment, the test client first sends a test request to the tested main body, so that the control device of the test state of the wind generating set controls the tested main body of the wind generating set to start the test according to the test request, and sends feedback information for determining to enter the test state to the test client through the tested main body.
The heartbeat information may be heartbeat information periodically sent by the test client. In this embodiment, the transmission period of the heartbeat information is not limited. Alternatively, the heartbeat information may not be periodically sent by the test client, and this is not limited in this embodiment.
Further, in this embodiment, the heartbeat information may be a pulse signal.
Specifically, in this embodiment, the test client sends heartbeat information to the tested subject of the wind turbine generator system between the time when the tested subject starts the test and the time when the test is terminated. If the test client does not have interference of uncertain factors, the tested main body of the wind generating set can receive heartbeat information sent by the test client, if the test client has interference of uncertain factors, the heartbeat information cannot be sent to the tested main body of the wind generating set, the tested main body of the wind generating set cannot receive the heartbeat information sent by the test client, the control device of the test state of the wind generating set controls the test state of the wind generating set according to whether the sent heartbeat information is received, and the test state is kept when the sent heartbeat information is received; and when the transmitted heartbeat information is not received, the test state is exited.
Specifically, in this embodiment, after the test on the tested main body is completed or the test is interfered by the uncertain factor, and the sending of the heartbeat information to the tested main body of the wind turbine generator system is stopped, the control device of the test state of the wind turbine generator system does not receive the heartbeat information within the preset time, then the control device sends the information for determining to exit the test state to the tested main body, the tested main body sends the information for determining to exit the test state to the test client of the wind turbine generator system, and the test client of the wind turbine generator system receives the information for determining to exit the test state of the tested main body, and indicates that the tested main body of the wind turbine generator system exits the test state.
According to the control method for the test state of the wind generating set, the test request is sent to the tested main body of the wind generating set; after receiving feedback information of a tested main body, which confirms to enter a testing state, sending heartbeat information to the tested main body; and after the heartbeat information is stopped being sent, receiving the information of the tested main body for determining to exit the test state. The control device of the wind generating set testing state can enable whether heartbeat information is received or not to serve as a basis for controlling the wind generating set testing state, interference of uncertain factors can be caused at a testing client, the control device of the wind generating set testing state can still exit from the testing state when a testing termination instruction is not received, normal power generation and monitoring of the wind generating set are prevented from being influenced, and the service life of the wind generating set is prolonged.
Fig. 4 is a signaling flowchart of a fourth embodiment of the method for controlling the test state of the wind generating set according to the present invention, and as shown in fig. 4, the method for controlling the test state of the wind generating set according to the present embodiment includes the following steps.
Step 401, a test client of the wind generating set sends a test request to a tested main body of the wind generating set.
It can be understood that, after the test client of the wind generating set sends the test request to the tested subject of the wind generating set, the control device of the test state of the wind generating set also receives the test request.
Step 402, the control device of the wind generating set test state controls the tested main body of the wind generating set to start the test.
And the control device of the test state of the wind generating set controls the tested main body of the wind generating set to start the test according to the test request.
Step 403, the control device of the wind generating set testing state sends feedback information for determining to enter the testing state to the testing client of the wind generating set through the tested main body of the wind generating set.
In this embodiment, the test client of the wind turbine generator system receives the feedback information for determining that the test state is entered, so as to determine that the tested subject of the wind turbine generator system has started the test.
Step 404, the test client of the wind generating set sends heartbeat information to the tested main body of the wind generating set, and sends a test termination instruction to the tested main body of the wind generating set after all the test data are obtained.
When the test client of the wind generating set is not interfered by uncertain factors and the communication is smooth all the time, the control device of the test state of the wind generating set can receive the heartbeat information through the tested main body. Once the test client is interfered by uncertain factors, the control device of the test state of the wind generating set cannot receive the heartbeat information.
Step 405, the control device of the test state of the wind generating set judges whether the sent heartbeat information is received, if so, step 406 is executed, otherwise, step 407 is executed.
And step 406, the tested body of the wind generating set keeps a test state.
Step 407, the control device of the test state of the wind generating set determines whether the time when the heartbeat information is not received reaches a preset time and determines whether a test termination instruction is received, if the time when the heartbeat information is not received reaches the preset time or the test termination instruction is received, step 408 is executed, otherwise step 406 is executed.
And step 408, the tested body of the wind generating set exits from the test state.
And step 409, the tested main body of the wind generating set sends the information of the tested main body for determining the test exit state to the test client of the wind generating set.
Specifically, whether the time when the heartbeat information is not received reaches the preset time is judged to judge whether the test client is interfered by uncertain factors in the test process, and whether a test termination instruction is received is judged to determine whether the test state needs to be normally exited. And when any one of the two conditions is met, the wind generating set is controlled to exit the test state.
In the method for controlling the test state of the wind generating set provided by this embodiment, the test client sends a test request to the control device of the test state of the wind generating set, the control device of the test state of the wind generating set controls the tested main body of the wind generating set to start a test, the control device of the test state of the wind generating set sends feedback information for determining to enter the test state to the test client through the tested main body of the wind generating set, the test client sends heartbeat information to the control device of the test state of the wind generating set through the tested main body of the wind generating set, and after obtaining all test data, sends a test termination instruction to the control device of the test state of the wind generating set through the tested main body of the wind generating set, and the control device of the test state of the wind generating set judges whether the sent, if so, controlling the wind generating set to keep in a test state, otherwise, judging whether the time for not receiving the heartbeat information reaches the preset time and judging whether a test termination instruction is received, if not, controlling the wind generating set to quit the test state, otherwise, controlling the wind generating set to keep in the test state, and after quitting the test state, receiving the information of determining the quit of the test state of the tested main body by a test client of the wind generating set. The method and the device can quit the test state under the condition that the test client is interfered by uncertain factors, and the phenomenon that the test state is accidentally quitted due to network delay is avoided. And the test client can exit the test state in time under the normal condition.
