Abstract

The invention relates to a safety guarantee method for full-automatic fault treatment of a power distribution network, and belongs to the field of automatic power distribution of power systems. The method comprises the following steps of enabling an automatic power distribution main station system to establish a memory topology of primary equipment of the power distribution network according to a topology model of the power distribution network; when the conditions occur in the power distribution network running process, such as equipment fault, terminal communication interruption and existing of persons in equipment fields, dispatching operation and maintenance persons to perform placard hanging operation on the faulty equipment in the system, and marking the condition of the equipment by different types of operation placards; when a feeder line of the power distribution network fails and needs to perform full-automatic fault treatment, enabling the main station system to judge whether the equipment is hung with the placard or not and judge the type of the hanged placard in the FA (failure analysis) process, determining whether the feeder line needs to take the special safety guarantee strategy or not according to the requirements, and guaranteeing the safety running of the power distribution network under the condition of automatic fault treatment without manual interference.

Description

technical field [0001] The invention belongs to the field of power system distribution automation, and relates to a safety guarantee method for automatic fault processing of a distribution network. Background technique [0002] Due to the complex operating environment of the distribution network, various problems occur frequently in the distribution equipment. When the distribution automation master station system executes the FA plan, most of them adopt the semi-automatic method that the dispatcher first reviews the FA plan, confirms that it is correct, and then executes it manually. Although this method ensures the correctness of the FA scheme, it reduces the efficiency of the FA scheme execution and prolongs the power outage time due to manual intervention. In order to further improve the power supply reliability of the distribution network, it is urgent to study the safety guarantee method for the fully automatic execution of the FA scheme. In the case of ensuring the sa...
