In conjunction with Fig. 1, set forth operation principle of the present invention:
Dispatching control center will continue to scan data, state, the warning message at boiler room control station and all thermal substation Long-distance Control stations, the validity of inspection data, and update system database.Dispatching control center is accomplished the fill order that all thermal substation Long-distance Control stations are transmitted for information about, received and assign.
Dispatching control center is accomplished the warning of system event through sound, picture; Can provide warning, dangerous second-level alarm to the process variables numerical value that transfinites; Warning can utilize computer to suppress or elimination by the operator; Warning can be on flow chart single-point show that and generation incident, the tabulation of reporting to the police comprise identifier, explanation, time etc.The computer of dispatching control center generates all kinds of forms; Form is the complex report forms based on the Excel form; Report interface is directly perceived, short and sweet, and the form kind comprises: incident, report to the police tabulation, equipment state record sheet, technological parameter history report, system's operation sheet.The printer that computer connects can print form according to operator's needs.
The boiler room control station is selected the CPU317-2DP controller for use, and this controller is programmable logic controller (PLC) S7-300 series of products in the Siemens.It has adopted modularization not have the fan design, and sturdy and durable, easy expansion and powerful network communication ability have multiple different communication interface, realizes distributed frame easily and has friendly user's operating characteristic.
Each thermal substation Long-distance Control station adopts a cover thermal substation Long-distance Control station system to accomplish data acquisition and control function separately; Controller adopts S7-226; The I/O subsystem adopts the expansion module mode, disposes the data and the flow process picture of local screen displaying thermal substation.First of network shooting is installed at each thermal substation Long-distance Control station, monitors field condition in real time, and picture is sent to dispatching control center.
Data communication between thermal substation Long-distance Control station and the dispatching control center adopts the ADSL network.
The real time execution situation of equipment in each thermal substation of dispatching control center remote reviewing through the transmission of communication apparatus, can be accomplished the real-time collection to each thermal substation data, after the comparison data, carries out analytical calculation, reaches a conclusion then.Carry out Long-distance Control by the gained conclusion, finally realize effective adjusting of heat supply network, arrive final balance.Each area thermal substation carries out PID through the temperature objectives value of setting and regulates the control to valve, also can receive the instruction that upper system call control centre assigns, and realizes once netting the control of backwater valve.
Larger central heating system, through the adjusting at each thermal substation place, the water supply of secondary net and backwater mean temperature are reached an agreement the most at last, thereby make the target room temperature of central heating be tending towards identical basically.The staff is called uniformity to the mode of this adjusting and regulates.Uniformity regulate to be exactly that to reach consistent be target with once netting the backwater mean temperature with the secondary net supply water temperature of each thermal substation; Regulate through each thermal substation is once netted the backwater motor regulated valve, thus reach each thermal substation in the system with the purpose of user's even distribution heating.Avoided the stow away from heat end subscriber not hot, closely leaned on the overheated pattern of heat source side user, the user's temperature that changes heat source side far away and nearly heat source side gradually into the adjusting that tends to balance.At last, also saved the energy, obtained heating effect well through this regulative mode.Mainly be because adopted the software that suitable uniformity is regulated, be referred to as the whole network Balance Control software with the exploitation of square company.
At first, at dispatching control center the host computer of control system is arranged, host computer adopts dual-computer redundancy-dereliction from apparatus-form; During normal the use; Two computer the using and the reserved, when master computer breaks down, redundant computer at once automatically input coefficient bear monitor task.The configuration net software electric power version of the inferior control in Beijing that relatively is fit to practical operation situation all is housed on the computer; Individual thermal substation corresponding real-time picture has been done by our company in configuration net software, and the whole network balance adjustment software that cooperates configuration software to use also is housed simultaneously on computers.Through each thermal substation picture of being done in the configuration net software; The staff collected once net supply backwater temperature; The whole network balance adjustment software draws an average criterion temperature through computing, if the secondary net of thermal substation supplies the backwater mean temperature greater than this target temperature; Then can close minor valve automatically, reduce the energy loss at overheated station through the configuration net.Otherwise,, improve the not temperature at hot station if mean temperature less than this target temperature, is then opened big valve.
Secondly; Thermal substation Long-distance Control station is the foundation that constitutes central heating heat supply network automated system; Imperative equipment is listed as follows in the thermal substation Long-distance Control station: measurement device: mainly by a secondary net supply and return water temperature transmitter in each thermal substation system, and secondary net teletransmission moisturizing table and once net the circling water flow rate meter.Operational outfit in standing: mainly by the circulating pump in the thermal substation system and matching used frequency converter thereof, secondary net small pump, once net the backwater electric control valve, once net backwater pressure pump and magnetic valve etc.The automatic controller at each thermal substation Long-distance Control station: because system has adopted digital governer; Really realized circuit controls; Each loop is relatively independent, breaks down in any loop, only needs to change the loop digital governer; Can not have influence on system's any part operation, make the risk of system and maintainability be distributed to the loop.
The purpose that the steady of system press device is set is that heating system can move, and does not turn, does not vaporize in the assurance system under the voltage stabilizing state.Adopt small pump frequency control level pressure, its basic principle is the pressure variation according to heating system, changes the running frequency of water pump, smoothly infinitely adjusts the small pump rotating speed, in time regulates rate of water make-up, realizes the constant control of system pressure volume.Capital equipment is a frequency converter, and operation principle is to transfer the alternating current of 50Hz to direct current, is transformed to the alternating current of another kind of frequency to direct current through frequency converter again, thereby reaches the purpose of small pump speed governing.
The principle of frequency conversion water circulating pump Energy Saving Control is that confession in the control heating system, return water temperature keep setting value, when thermic load changes, regulates the size of quantity of circulating water automatically and deacclimatizes the needs that system loading changes, and replaces the uneconomical way of valve regulation and control in the past.The supply and return water temperature of heating system converts current signal or voltage signal to by transmitter; Feed back to the PID adjuster; It is compared temperature feedback signal with the setting signal value; And after the many links of PID are regulated, obtain the operating efficiency of the given signal controlling frequency converter of frequency, thereby the rotating speed of control water pump and the water yield of water pump.That is to say, when the exit of pump temperature is lower than setting value, the frequency converter frequency that raises automatically, water pump commentaries on classics degree improves, and the pump discharge temperature rises; When the exit of pump temperature was higher than setting value, frequency converter reduced frequency automatically, and pump rotary speed descends, and the pump discharge temperature descends, and it is poor to keep design temperature.
Fuzzy control theory of economize on electricity control utilization computer and converter technique according to the variation of end load, are gathered multiple running parameter.Calculate through the load servo-actuated then, automatically water pump is carried out real-time optimization control, guarantee that system under the prerequisite that satisfies supply rationally, reduces system's energy resource consumption significantly.Regulate the difference of parameter according to system; The control model of energy-saving control system is by three types: first kind is the system of automatically locking; As according to the temperature value of setting as regulating parameter, make it the deviation that keeps invariable or be no more than appointment, be referred to as regularly regulating system usually; Second kind is program regulation system, promptly with time is to regulate parameter, comes the running status of regulating system according to the given function of time in advance, and being also referred to as is regulating system surely; The third is a servo regulation system, and regulating according to indoor temperature and humidity value of setting and the difference between the outdoor natural temperature is exactly the follow-up adjustment of standard.These three kinds of patterns can be changed setting arbitrarily according to user's needs.
It is emphasized that; Embodiment of the present invention is illustrative; Rather than it is determinate; Therefore the present invention is not limited to the embodiment described in the specific embodiment, and every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention belong to the scope that the present invention protects equally.
