Embodiment Construction

[0090] Such as figure 1 As shown, a substation automation system, the substation automation system combines and optimizes the secondary equipment of the substation (including measuring instruments, signal systems, relay protection, automatic devices and telecontrol devices, etc.) Technology, modern electronic technology, communication technology and signal processing technology, realize the automatic monitoring, measurement, automatic control and microcomputer protection of the main equipment and transmission and distribution lines of the whole substation, and comprehensive automation functions such as communication with the control center.

[0091] The substation automation system is abstracted into a three-layer architecture according to function and logical communication: substation layer, bay layer, and process layer.

[0092] The process layer is the interface between primary equipment and secondary equipment. The main functions of the process layer are divided into three...

Abstract

A transformer station automatic system performs functional combination and optimized design on secondary equipment (including a measuring instrument, a signal system, relay protection, an automatic device, and a telecontrol device) of a transformer station so as to achieve comprehensive automatic functions of the main devices of the transformer station, a power transmission line, and a power distribution line by using advanced computer technology, modern electronic technology and communication technology, and signal processing technology, wherein the comprehensive automatic functions includes automatic monitoring, measurement, automatic control, microcomputer protection, and communication with a control center.

Description

technical field [0001] The invention relates to the technical field of substation control in a power grid system, in particular to a substation automation system. Background technique [0002] The substation is an important part of the power transmission and distribution system. The traditional secondary circuit of the substation is composed of various devices such as relay protection, local monitoring, telecontrol device, fault recording and ranging, DC system and insulation monitoring and communication. . They each use independent devices to complete their own functions and are self-contained systems, which inevitably leads to mutual coverage of functions between various devices, repeated configuration of components, and consumption of a large number of connecting wires and cables. At the same time, the maintenance workload is heavy and the reliability of the equipment is poor, which is not conducive to improving the level of operation management and automation; it does n...
