Communication management system for static var compensator (SVC)

Abstract

The invention provides a communication management system for a static var compensator (SVC). The communication management system comprises a management module, a protocol transfer module, an AVC interface module, a transfer data backup module, a shared database module, a latching logic module, a data screening module, a protocol access module and an access data backup module, so that seamless connection of the SVC, an integrated automatic system of a substation and a dispatching automation system is achieved. The communication management system provided by the invention can meet the special requirements of a SVC controller and a SVC communication system; a protocol module is abstracted into a data object, a channel object, data realization and a communication process; the data object, the channel object and the data realization are all finished in a base class; a derived class module only finishes realization of the communication process; a base class mapping method is adopted by data correspondence terms in different protocols; and development of the protocol module is greatly simplified.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a communication management system for SVC. Background technique [0002] Static var compensator (Static varcompensator, SVC) is a static parallel reactive power generating or absorbing device, it can quickly change the reactive power it sends out, has a strong reactive power adjustment capability, and can provide dynamic power for the power system. The reactive power supply compensates the system voltage to a reasonable level. By dynamically adjusting reactive power, SVC suppresses bus voltage fluctuations caused by grid faults, which is beneficial to transient voltage recovery and improves system voltage stability. [0003] The secondary system of SVC involves multiple units such as adjustment unit, protection unit, valve base electronic unit, input unit, output unit, and measurement unit. For the interior of the SVC device, each unit uses a dedicat...

AI Technical Summary

Problems solved by technology

[0010] To sum up, the existing conventional communication management system for substations cannot realize the above functions well, and the development of a special communication management system for SVC can realize the seamless connection between SVC and substation integrated automation system. Full monitoring of SVC

[0011] In addition, for the conventional protocol conversion function, the integrated automation system of the connected substation and the monitoring of the dispatching terminal are different, and the protocols used are also different. Therefore, a large amount of manpower is required in the development and maintenance of the protocol.
