A Monitoring System of Series Capacitor Compensation Device

Abstract

The invention relates to a monitoring system for a serial connection capacitor compensating device, which adopts an object-oriented abstract modeling method and comprises a communication management module, a configuration information module, a real-time data processing module, an interface management module, a history data management module, a control function management module and an auxiliary function module, wherein the communication management module, the interface management module, the history data management module, the control function management module and the configuration information module are respectively communicated with the real-time data processing module, the auxiliary function module is respectively communicated with the control function management module, the interface management muddle and the communication management module, and the interface management module is communicated with the control function management module. in the monitoring system, the modularized layered design thought is adopted, each module independently operates, the operation of other modules can not be influenced by the exiting of one module, and thus, the safety, the reliability, the stability, the reusability and the universality of the monitoring system operation are ensured.

Description

technical field [0001] The invention belongs to the field of power systems and relates to a monitoring system, in particular to a monitoring system of a series capacitor compensation device or an ultra-high voltage series resonance type fault current limiter. Background technique [0002] The series capacitor compensation device can equivalently shorten the electrical distance of the transmission line and improve the transmission capacity of the transmission line, and its operation status is related to the operation mode and safety of the power grid. The series capacitor compensation device is divided into a primary system and a secondary system. The primary system refers to the equipment directly connected to the transmission line, and the secondary system is composed of a control protection system and a station control layer system. The control and protection system provides automatic control and protection of primary equipment, and the station control layer system provide...

Problems solved by technology

There are two main types of monitoring systems for existing series capacitor compensation devices. One is the general substation monitoring system. Since its function is mainly for conventional substations, that is, substations without series capacitor compensation devices and other equipment, it is similar in function to series capacitor compensation devices. At the same time, the system of the entire monitoring system is huge, and it is inconvenient to install, debug, use and maintain, which is not conducive to the debugging and daily operation and maintenance of the series capacitor compensation device; the second is the monitoring system customized according to the actual project. The structure is relatively simple, but it is aimed at a specific project. Each series compensation project usually has its own special requirements. Therefore, the monitoring system needs to be redeveloped accordingly. Although the function is better compatible with the series capacitor compensation device, but Less reusable or general
