Intelligent high-voltage switch interlocking logic testing method supporting IEC61850 stipulations

Abstract

The invention relates to an intelligent high-voltage switch interlocking logic testing method supporting IEC61850 stipulations. The method comprises the following steps that (1) an interlocking logic formula is input to a high-voltage switch interlocking logic testing software functional module, and a computer automatically generates an interlocking logic testing scheme; (2) the computer sends out a control signal to close a connecting port between an intelligent terminal and a switch; (3) the computer sends a high-voltage switch position signal to a measurement and control device according to the interlocking logic testing scheme, a position variable of an element in interlocking relation with a disconnecting link tool to be measured in the measurement and control device is modified, simulation station level equipment sends an instruction to the measurement and control device to control the disconnecting link tool to be measured to act, the measurement and control device sends out an action instruction or an action rejection instruction, and the computer records the instruction. By means of the method, the problems that manual interlocking logic testing does not conform to the interlocking logic judgment flow in the practical running process of an intelligent high-voltage switch, an operation error is prone to occurrence, the workload is large, and testing time is long are solved, and mechanical wear to primary equipment is reduced.

Description

technical field [0001] The invention relates to an intelligent high-voltage switch interlock logic inspection method supporting the IEC61850 protocol. Background technique [0002] Judging from the functional characteristics of the circuit breaker and isolation / grounding switch, when the line or equipment is in normal operation (that is, there is voltage and current), if the power failure operation is performed, the only way is to disconnect the circuit breaker, separate the isolation switch, and close the grounding switch. The order of the knife switch is called the operation logic of the primary equipment. On the contrary, the operation of equipment commissioning can only be carried out in the order of opening the grounding switch, closing the isolation switch, and closing the circuit breaker. The operation logic of one-time equipment commissioning and power failure is also called intelligent high-voltage switch interlock logic. Each isolation / grounding switch has an inte...
