High voltage DC power transmission converter station real-time monitoring system and its realizing method

Abstract

The invention relates to a high-voltage direct-current transmission detecting system and relative method, wherein it is formed by data collector, server and user terminal; the server comprises a forward data server, a real-time data server, a communication manage server and a history data server; the user terminal displays variable data information and supply graph detecting operation; he collector converts the collected analogue signal into digit signal, via network to be sent to the forward data server; the forward data server processes and calculates out relative signal value, and transmits the data to the real-time data server; the real-time data server stores the digit signal value, according to the request of user terminal, to send displayed data to relative user terminal, or transmit the user operation command via forward data server to the operator; the operator will control the executer to complete the operation; the server has stable and reliable operation; the user interface is friend, with simple operation.

Description

technical field [0001] The invention belongs to the technical field of automatic control systems, specifically a high-voltage direct current transmission monitoring system and its implementation method, which uses computer network technology to centrally monitor and control a high-voltage direct current transmission converter station in real time, and save the real-time data Come down for later reference and analysis. Background technique [0002] The monitoring system is the monitoring and control system, which is a system that uses computer network technology and computer graphic display technology to display the operation of the entire HVDC converter station and control the operation status of the entire station. The switching signals in the converter station are generally provided upwards in the form of nodes, and the measurement quantities are generally provided upwards in the form of current or voltage. After being collected and processed by the acquisition unit, these...

Problems solved by technology

[0004] At present, the domestic high-voltage direct current transmission operation personnel monitoring system is supplied by foreign manufacturers, and there are large differences in function, performance and usage habits with domestic users, mainly in: the operation personnel monitoring system based on the multi-user operating system UNIX The interface is not friendly enough, especially complex Chinese-style reports and other functions cannot be realized, the database function is not powerful enough, and it basically belongs to the English interface, and the Chinese content is limited; the operating personnel control system based on the Windows operating system has poor stability and is vulnerable to virus infection and attack Wait
