High-and-low-voltage cabinet long-distance programmed control system and method

Abstract

The invention discloses a high-and-low-voltage cabinet long-distance programmed control system and a method. The high-and-low-voltage cabinet long-distance programmed control system comprises an upper computer system monitoring layer, a communication management layer and a field protection measurement and control unit layer, wherein the upper computer system monitoring layer comprises a satellite clock receiving and synchronizing system, a server and a monitoring host; the server is communicated with the satellite clock receiving and synchronizing system and the monitoring host; the communication management layer comprises a main control unit and realizes uploading and issuing of various data and instructions; and devices of the field protection measurement and control unit layer are communicated with the upper computer system monitoring layer through the communication management layer. The beneficial effects are that control signals, protection signals, measurement signals, alarm signals and the like are processed into data information in a local unit on the basis of a microcomputer integrated relay protection device and a measurement and control device and then transmitted to a monitoring computer in a main control room through a field communication bus, thereby fully meeting requirements such as measurement, protection, control and the like of users for electrical equipment.

Description

technical field [0001] The invention relates to the technical field of remote control of switch cabinets, in particular to a remote program control system and method for high and low voltage cabinets. Background technique [0002] At present, the distributed control system (DCS) of power plants led by thermal automation has been widely used, but most of them focus on steam turbines and boilers, and less consideration is given to the electrical system. The control and automation level between the boiler and the electrical system uncoordinated. The electrical automation system of traditional power plants uses physical hard wiring and a large number of hardware devices such as transmitters and I / O cards to collect electrical information and control electrical equipment. Information such as measurement, protection action, setting, and accident recall of the electrical system cannot be accessed on the DCS. Fully responding, it is impossible to realize the functions of electrical...
