Abstract

The invention provides a method for realizing concentrated monitoring of substation's remote tele-signal interpretation function. The method comprises the following steps: establishing a first remote tele-signal interpretation module and a second remote tele-signal interpretation module; adding the second interpretation module between a market monitoring system and a station backstage monitoring system; adding the first interpretation module between the station backstage monitoring system and a substation device; and establishing a visible monitoring interface between the market monitoring system and the station backstage monitoring system to display respectively the remote tele-signal error warning signals outputted from the second interpretation module and the first interpretation module. In the invention, substation remote tele-signal interpretation modules are introduced to resolve the monitoring problem under these abnormal conditions. Maintenance workers can monitor whether the second interpretation module and the first interpretation module output tele-signal error warning signals or not based on the visible monitoring interface between the market monitoring system and the station backstage monitoring system so that prompt repair work can be conveniently made to ensure that the power grid works stably and safely.

Description

technical field [0001] The invention belongs to the technical field of remote signal interpretation of centralized monitoring substations, in particular to a method for realizing the function of remote signal interpretation of centralized monitoring substations. Background technique [0002] In the operation of the power system, the closing or opening of the circuit breaker will directly affect the structure of the power grid, so it is very important information in the monitoring of power grid dispatching operation. In addition, the position status of the isolating switch and the working conditions of the relay protection and automation devices are also of concern to the operation and maintenance personnel. These information usually take two states: "closed" and "open", which can be represented by one bit two source codes. According to the IEC standard of the International Electrotechnical Commission, "0" means the open state; "1" means the closed state. Remote signaling i...
