Integrated automation system of power station

Abstract

The invention discloses an integrated automation system of a power station. The integrated automation system comprises a station control device, the Ethernet in communication with the station control device, a plurality of main control units connected with the station control device through the Ethernet, a plurality of unit electrical system devices, a plurality of unit side public electrical system devices and a plurality of power station booster station system devices, wherein the unit electrical system devices, the unit side public electrical system devices and the power station booster station system devices are connected with the main control units respectively. The unit electrical system devices, the unit side public electrical system devices and the power station booster station system devices are divided into multiple groups to be connected through field buses to form networks, and the unit side public electrical system devices and the power station booster station system devices are connected to the Ethernet through the main control units to form a public electrical system network. According to the integrated automation system, the defects of a traditional ECMS on operation on and control over electric devices for the station are overcome, and the problem that the original ECMS and an original NCS are independent and can not smoothly carry out data exchanging is solved.

Description

technical field [0001] The invention relates to the field of power plant control systems, in particular to a power plant comprehensive automation system. Background technique [0002] Traditional power plants use DCS (Distributed Control System) as the main control system of the unit unit. The field equipment mainly uses traditional analog and switch signals, that is, 1-to-1 analog or binary signal transmission, that is, each measuring point passes Hardwired to the DCS system I / O card. As super-large-capacity generator sets are put into operation one after another, the operation and control of the electrical part of the unit is becoming more and more complicated. However, the DCS of the power plant focuses on the machine furnace, and less consideration is given to the electrical system. The measurement and protection actions of the power system of the power plant , Accident memories and other information can only enter the DCS limitedly through hard contacts, forming a rela...

Problems solved by technology

[0005] Regrettably, the current plant electrical monitoring system ECMS and the booster station network computer monitoring system NCS are two completely separated systems. The plant power and the booster station power network lack data interaction channels, and the host / operation The personnel stations are set up independently, resulting in repeated allocation of resources, which is also not conducive to the power plant operators' grasp of the overall situation
