Embodiment Construction

[0022] The invention is a method for realizing remote signaling data identification of substation topology network, including:

[0023] Step 1. According to the voltage levels contained in the substation, divide the substation into networks of different voltage levels. These networks usually end with transformer windings and form a star network with the bus as the center;

[0024] Step 2. In each network, the bays are regarded as a whole, and these bays as a whole are topological nodes connected to the bus to form a topological network;

[0025] Step 3. Use three levels of logic analysis for this special topology network to identify bad remote signaling data;

[0026] Step 4. The three levels of logical analysis are: logical analysis of a single device inside a bay, logical analysis between devices inside a bay, logical analysis between bays, and finally eliminate bad remote signals.

[0027] During specific implementation, a method for realizing remote signaling da...

Abstract

The invention relates to a method for achieving transformer substation topology network telecommand data identification, and belongs to the technical field of electric power. A logical relationship of telecommand data are telemetered through different network nodes in an integrated monitoring system, and a three-grade logical judgment method is used for identifying the telecommand state in a topology network. The method has the advantages that poor telemetering telecommands can be eliminated, it is guaranteed that the telecommand data in topology analysis are accurate, and interference of bad data to various service applications of a transformer substation is reduced. High redundant multisource metering information in the transformer substation can be effectively used, the identification rate of the bad data is improved, and the anti-interference capability of the system is strengthened.

Description

technical field [0001] The invention relates to a method for realizing remote signaling data identification of substation topology network, which belongs to the field of electric power technology. Background technique [0002] In the analysis of substation power system, the measurement data of some important nodes, such as voltage, current, power, remote signaling, etc. in the network, usually have redundancy in the system where it is located or in other systems. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a method for realizing remote signaling data identification of substation topology network. The purpose of the method is to solve the problem that in the prior art, in the analysis of the power system of a substation, the measurement data of some important nodes are redundant in the own system or in other systems. [0004] The technical solution adopted by the present invention to so...
