Operation method of mobile power generation system connected to power grid using backup and self-switching technology

Abstract

The mobile power generation system adopts the standby self-switching technology to connect to the power grid operation method, and uses the load transfer system and power generation system with dual-power backup automatic switching control device for operation; the load transfer system includes the first backup automatic switching control device (1DL) , The second standby automatic switching control device (2DL) and the external connection cable (L) with the first load switch (K1) connected between the two power sources, and the second one installed on the front cable of the first standby automatic switching control device The load switch (K2), the mobile power generation system (C) and the third load switch (K3) connected to the rear cable of the second standby automatic switching control device; when the 10kV line (1) needs maintenance, disconnect the line The back-end load at point (A) is powered by the mobile power generation system; when the line needs to be repaired, the back-end load at the disconnection point of the line is powered by the mobile power generation system. The invention can realize seamless switching with mains power, realize fast response and handling of emergencies, realize comprehensive non-stop maintenance of distribution network, and improve power supply reliability.

Description

technical field [0001] The invention belongs to the technical field of bypass live operation, and is suitable for the case where some equipment of a 10kV line needs power outage maintenance. In order to ensure the continuous power supply of the back-end load in the maintenance section, the back-end load of the maintenance point can be treated by using the principle of live operation and section backup self-input Realize uninterrupted power supply. Background technique [0002] With the economic and social development of the country and the improvement of people's living standards, the requirements for power supply reliability and power quality are getting higher and higher, and the dependence is getting stronger and stronger. As a working method such as backup power supply, the generator car cannot avoid short-term power outages on the 10kV line, and can no longer meet the customer's requirements for power supply reliability. In order to improve the reliability of power sup...
