Description
Technical field
The system of alarm and control when the utility model relates to a kind of Rural Power Distribution Network fault, overload.
Background technology
Along with the change of rural economy situation and the raising of agriculture, rural areas and farmers need for electricity level, the contradiction that rural economy high speed development and Rural Power Grid Construction level relatively lag behind is day by day obvious, and the contradiction between electricity for rural use Continued and rural power grids power supply capacity deficiency is becoming increasingly acute.Rural power grids have the self-characteristic being different from urban distribution network, and the equipment annual underloading time is long, and Rate of average load is low, and peak amplitude is high, and peak value rises year by year; The change of three-phase imbalance rate is fast, and be not easy adjustment, manual measurement is wasted time and energy, and can not truly report situations again; Power load seasonal characteristic is obvious, greatly influenced by ambient temperature, particularly the Spring Festival and summer peak of power consumption power supply capacity not enough and voltage is low, customer complaint is many, as carried out invest in the transformation of real estate according to peak load value, scale of investment is large, will cause the long-time light running of equipment, loss is large, and current state's financial capacity cannot realize.
At present, market there are some load management Terminal Type equipment, but its function is confined to after the load current of user load end is continued above set point (setting value), just send alarm signal and the load of excision overload successively, its function singleness and need manual reversion power transmission, can not recover, automatically if be used in platform district, rural area, interruption duration is long will cause more complaint, effectively can not solve rural area Overload in short-term.
Utility model content
Technical problem to be solved in the utility model is, one is provided to realize tripping operation in turn to overload loop and automatically to recover, serious overload loop is directly excised, can effectively guide rural area peak load and control, reduce the complaint of client, invest little, the system of alarm and control when the Rural Power Distribution Network fault that result of use is good, overload.
For solving the problems of the technologies described above, the Rural Power Distribution Network fault that the utility model provides, the system of alarm and control during overload, it comprises the intelligent terminal that controlling center and several and controlling center communicate to connect, the control loop of each intelligent terminal is all connected with the power line of the earth leakage protective device on all transmission line circuits of corresponding power distribution station, controlling center and intelligent terminal are by GPRS/CDMA wireless connections, described controlling center comprises information receiving device, messaging device, information transmitting apparatus, key-press input equipment and display device, described intelligent terminal comprises PLC control module and carries out the communication module of communication with controlling center.
After adopting above structure, the utility model compared with prior art, has following advantage:
Can the phase current of Real-Time Monitoring each power distribution station Circuit Fault on Secondary Transformer by controlling center, and pass through at controlling center setup control policy distribution to each intelligent terminal, when intelligent terminal detects that phase current exceedes different overload electric currents and the overload time of setting respectively, intelligent terminal can carry out sending overload alarm respectively, excise the transmission line circuit of corresponding transformer in turn, the operation that all transmission line circuits of the corresponding transformer of direct excision etc. are different, can tripping operation in turn be realized to overload loop and automatically recover, serious overload loop is directly excised, and intelligent terminal can also be monitored three-phase imbalance rate, when monitoring after three-phase imbalance rate exceedes set point, three-phase imbalance alarm can be sent, can effectively guide rural area peak load by above system and control, reduce the complaint of client, invest little, result of use is good.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the overload alarm of the utility model rural power grids and control;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model Rural Power Distribution Network fault, during overload, the system of alarm and control comprises the intelligent terminal that controlling center and several and controlling center communicate to connect, and controlling center comprises information receiving device, messaging device, information transmitting apparatus, key-press input equipment, display device etc., the control loop of each intelligent terminal is all connected with the power line of the earth leakage protective device on all transmission line circuits of corresponding power distribution station, controlling center and intelligent terminal are by GPRS wireless connections, described earth leakage protective device is connected in series by earth leakage protective device and A.C. contactor and forms, described intelligent terminal comprises PLC control module and carries out the communication module of communication with controlling center, intelligent terminal and rural power grids intelligence distribution transformer terminals, it is to distribution transformer, line switch, RCD, the operation informations such as intelligent electric energy meter carry out gathering and user power utilization information carries out the equipment collected, complete distribution transformer metering summary table and monitor, RCD is monitored, status monitoring, load management, dynamic passive compensation/three-phase imbalance improvement/harmonic wave control, security protection, interactive management, asset management, the functions such as environmental monitoring and distributed power source access-in management.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection range of independent claims of the present utility model are all in protection range of the present utility model.
