Main distribution integrated load transfer method for high-quality power supply service

Abstract

A main distribution integrated load transfer method for high-quality power supply service comprises the following steps: (1) determining faulty equipment and power loss load: determining the faulty equipment through a fault alarm function of a main station end comprehensive intelligent alarm application, and calling an auxiliary decision to determine the power loss load; (2) searching a main distribution integrated power supply path and generating a candidate scheme; (3) main and distribution integrated power flow verification and optimal path scheme determination: determining an optimal pathscheme based on candidate scheme power flow safety verification of main and distribution integrated operation data; (4) determining a high-quality power supply service-oriented main and distribution integrated load transfer operation sequence; and (5) calling an adaptive correction processing strategy when the switch operation is obstructed. By utilizing the method and the system, the problem thatcooperative rapid recovery cannot be realized under a large-scale power failure accident due to mutual independence of main and distribution network accident recovery can be solved, and main and distribution integrated whole-network rapid load transfer under a power grid fault is realized.

Description

technical field [0001] The invention relates to an automatic generation method for a load transfer scheme, in particular to a main-distribution integrated load transfer method for high-quality power supply services. Background technique [0002] As the daily operation of regional power grids is increasingly overloaded, over-limited, faulty, overhauled, and changed in operation mode, users have higher and higher requirements for power supply quality and power supply reliability. [0003] When the power grid fails, the emergency strategy for load recovery can be given in time, which can effectively control the further development of the power grid accident, shorten the time for the power grid to resume normal operation, and reduce the losses caused by the power grid accident. On the other hand, accident prediction, simulation calculation and other methods can be used to simulate the treatment plan in the event of an accident, providing decision-making basis and means for emerg...

Problems solved by technology

Although the existing main network control system can automatically locate the faulty equipment in the event of a grid fault, and provide information such as the scope of the outage caused by the fault, due to the lack of relevant information on the distribution network, it is impossible to subdivide the number of users affected by the fault and the number of users. Power supply level, it is difficult to assess the impact of faults in time, and it is difficult to realize the rapid load transfer of the entire network with priority for important users
