Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0020] The network structure of the power station control system of the present invention includes at least two unit units and a set of public systems, and each system adopts a master-standby redundant dual-network design. The connection between the various systems can be found in figure 1 As shown in the figure, the part between the two vertical dotted lines is the public system (G domain), and the two sides of the vertical dotted line are unit units, respectively A system (A domain) and B system (B domain). Connected through a dedicated router, the thick line shows the primary connection ring network, and the thin line shows the standby connection ring network. Networking betwe...

Abstract

The invention discloses a special router-based control system for a power plant public system, which comprises a public system control domain and at least two unit set control domains, wherein the public system control domain and each of the unit set control domains are connected by the special router. The unit set control domains and the public system control domain are connected by the special router and the redundant design can be realized through a main router and a backup router, so that that the control over the public system can be switched safely and reliably between unit sets is ensured, and the control is monitored and operated safely and reliably by the unit set at any time. The monitoring of the unit set on the public system refers to the monitoring of the public system by MMIsites on the unit set.

Description

technical field [0001] The invention relates to a power station control system, in particular to a control system when a plurality of unit units in a power station share a common system. Background technique [0002] In the control of power stations, unit units and public systems in DCS (Distributed Control System) are the most widely used structures in modern power stations, that is, two or more unit units share a common system, which provides various The control of auxiliary systems such as electricity, gas, water, ash, coal, and slag necessary for the unit unit to make the unit unit operate safely and stably. The importance of the public system is that once it is unmonitorable or uncontrollable, all units using the public system will be forced to shut down. Therefore, the public system cannot be merged into a unit unit for centralized control, but the public system must be guaranteed to be safe and reliable. Switching, so that there is a unit unit that can monitor and op...
