Method for actively studying and judging power distribution network fault based on public/specific transformer information

Abstract

The invention relates to a method for actively studying and judging power distribution network faults based on public / specific transformer information, and belongs to the field of power distribution automation of power systems. The method comprises the following steps: establishing memory topology of primary equipment of a power distribution network by using a power distribution network topology model through a power distribution automation host station system, and recording historical topology relationship before the equipment is powered off; acquiring relevant information through the power distribution automation host station system, and directly transmitting a distribution transformer measuring instruction through a power distribution host station; when a feeder line of the power distribution network has faults and the power is cut off, triggering active studying and judgment calculation through the power distribution host station according to the power-off event; confirming distribution transformer range and trip equipment which causes power off at the moment according to the study and the judgment of the designed logic algorithm; enabling a power distribution automation host station system to interact with a GPMS system, processing by a scheduling operator, performing power-off information issuing operation on the power distribution host station system directly, and synchronously updating the work order state of processing of the GMPS system to the power distribution host station system. Due to application of the active studying and judging method, the scheduling operator can be rapidly prompted in time and the power-off range and the trip equipment can be provided before power-off users request for repair, the activeness and the intelligence in the power-off rush repairing process are improved, and the power distribution rush repair working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of power system distribution automation, and relates to a method for actively researching and judging distribution network faults based on public transformer information. Background technique [0002] With the continuous advancement of the construction of the power system distribution network system and its practical functions, higher and higher requirements are put forward for the distribution network dispatching and emergency repair work, especially for the timeliness and accuracy of power outage fault handling. sexual indicators. [0003] Mainly for the blind area of ​​distribution network automation, the traditional dispatching work mode is generally: the power outage event is notified to the dispatcher by the user through telephone repairs, etc., and the dispatcher determines the power outage range according to the user who reports the repair; the dispatcher mainly relies on experience or at the same time.

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that traditional feeder automation technology cannot be used to monitor and analyze the blind area of ​​distribution network automation, which affects the efficiency of distribution and rescue work. When a power failure occurs on the network, the distribution automation master station system can actively analyze and quickly locate the tripping device and the scope of the power failure, and release the power failure information in time
