Intelligent disordered reverse feeding prevention method for power system

Abstract

The invention provides an intelligent disordered reverse feeding prevention method for a power system, and belongs to the field of power direction control. The intelligent disordered reverse feeding prevention method comprises a power supply network and a user having power generation equipment, wherein the power supply network is connected with the user having power generation equipment through a power supply line; a load control terminal and a gateway intelligent electric meter are arranged on the power supply line; the intelligent disordered reverse feeding prevention method is characterized in that a remote control switch is arranged on the power supply line; an electric operation end of the remote control switch is connected to the gateway intelligent electric meter, the load control terminal and a scheduling system of the power supply network; the gateway intelligent electric meter, the load control terminal and the scheduling system of the power supply network control on / off of the remote control switch through a power direction on the power supply line; different control modes are implemented aiming at different users; and reverse feeding of the users is effectively controlled.

Description

technical field [0001] The invention provides an intelligent power system anti-disorder reverse power transmission method, which belongs to the field of power direction control. Background technique [0002] With the gradual increase of power generation equipment for enterprises or ordinary power users, similar to electric vehicles, large batteries, solar panels, etc., which have the possibility of reverse power transmission, it is very likely that the power will be reversely sent into the power supply network through the transmission line, which will cause The electric energy of the power supply network is in disorder, and at the same time, it is very possible that the line that has been disconnected upstream may be charged during maintenance, which is very dangerous; users with power generation equipment are often divided into two categories, one is to The power supply network management unit applied for and was approved, and the other type was not approved by the power su...
