Method for improving switching operation accuracy of power supply system

Abstract

The invention discloses a method for improving the switching operation accuracy of a power supply system, and belongs to the field of safer running of power systems. The method comprises the following steps: dividing an administrative region; filling large operation orders between dropping stations; acquiring the current and voltage of all electrical equipment, the opening and closing positions of circuit breakers, the positions of grounding switches and remote measurement and remote communication data in the dropping stations to an integrated automatic system; performing communication between superior and inferior dropping stations by adopting optical fibers; transmitting position signals of the grounding switches of incoming line spaces of the inferior dropping stations to the superior dropping stations through an optical fiber network; installing interlocking programs of five-prevention analogue screens. According to the method, various types of misoperation accidents between the dropping stations and in the dropping stations are effectively avoided, damage to the electrical equipment is reduced, and the switching operation accuracy is effectively improved.

Description

technical field [0001] The invention belongs to the field of electrical safety production, and in particular relates to a method for improving the correct rate of switching operation of a power supply system. Background technique: [0002] The high-voltage switchgear has a reliable five-proof interlock, which can effectively avoid misoperations such as electrified closing and grounding knife switches, and closing and grounding knife switches for wrong power transmission. However, there is no such interlocking device between the upper and lower circuit breakers between the step-down station and the step-down station, and the power dispatcher is often contacted to confirm the power transmission. Often due to human reasons, the wrong operation of switching on and transmitting power with the ground wire will cause vicious accidents such as power grid fluctuations or three-phase short circuits. Contents of the invention [0003] The purpose of the invention is to effectively ...
