Abstract

This invention provides a laminated SVC monitor platform including a bottom layer, a middle layer and a top layer, among which, a communication manager, a SVC branch microcomputer protection unit, an auxiliary protection unit, a water-cooling system monitor and a VBE are set at the bottom of the monitor platform and are connected with the middle layer via RS232 and RS485 serial interfaces and realize the bottom distribution communication in series, the middle layer includes a site control, a station control, an adjusting unit and a master monitor unit, which are connected with each other via the CAN and realize the middle layer communication in the point to point way, the top of the monitor platform is the upper level automatic system communicating with the middle layer in terms of CDT.

Description

technical field [0001] The invention relates to a static var compensator (SVC) monitoring platform with a layered distributed structure. Background technique [0002] The static var compensator monitoring platform is the hardware and software basis of the SVC control system. It is a general name for the structure of the SVC control system and plays a decisive role in the reliable operation of the SVC device. The field bus (Field Bus) used in it is an advanced industrial measurement and control technology that emerged in the 1990s. It is a product driven by the market's requirements for intelligent field instruments and fully digital measurement and control systems. It brings the concept of communication network and management into the world. The field of industrial measurement and control. In essence, it is a digital communication protocol, a digital, two-way transmission, fully distributed, multi-branch communication network connecting intelligent field devices and automat...
