Problems solved by technology

It can be seen that this method requires a full-line power outage during the test process, which affects the reliability of power supply; in addition, it is difficult to organize and coordinate, and the work efficiency is low; the fault current is not easy to synchronize, it is difficult to guarantee the success rate of one-time test, and it is impossible to display the test process intuitively. Simulation data is prone to errors, reducing the accuracy of the simulation system

Abstract

The invention provides a feeder automation simulation system. The feeder automation simulation system comprises a control circuit, a primary circuit, a secondary circuit, a grounding contactor controlcircuit, contactor control circuit for short-circuiting and a self-locking protection circuit, wherein one end of the grounding contactor control circuit is connected to a live wire L via a switch Kwhile the other end is connected to a null wire N; one end of the self-locking protection circuit is connected to a live wire L via a switch K while the other end is connected to a null wire N; and one end of the control circuit, one end of the primary circuit and one end of the secondary circuit are connected to the live wire L via switches K while the other ends are connected to the null wire N.The feeder automation simulation system not only can stimulate grounding faults, but also can stimulate short-circuiting faults, reality simulation can be implemented effectively to meet demands, anddata detection is accurate.

Description

technical field [0001] The invention belongs to the technical field of power systems, in particular to a feeder automation simulation system. Background technique [0002] With the continuous deepening of smart grid construction, with the goal of continuously improving the reliability of distribution network power supply, the construction and transformation of distribution network feeder automation has gradually increased, and the level of distribution network security management and distribution network safe and reliable operation has been continuously enhanced. . In order to better promote the demonstration application of the distribution network and demonstrate the development performance and achievements of the distribution network, the feeder automation of the distribution network needs to be simulated and displayed. The FA function of the traditional feeder automation system often adopts the method of manual synchronous triggering. The tested line is powered off, and ...
