Abstract

A controller cluster device applied to a thermal power plant comprises two or more base plates, eight slots are evenly distributed in each base plate, each slot corresponds to one controller, and eachcontroller is connected to a base plate slot through a redundant PCIE bus. Every two adjacent bottom plates are connected through a redundant PCIE bus, all controllers in the device are arranged in acluster mode and are connected with one another with the bottom plates as links, a redundant PCIE bus network is constructed, and data interaction is conducted between the controllers through the redundant PCIE bus. The controller adopts a dual-computer hot standby mode, a pair of redundant controllers is formed by a main controller and a standby controller, and a redundant gigabit Ethernet interface is designed on each controller. According to the device, the data interaction speed between the controllers can be greatly improved, the undisturbed switching performance of the dual-computer hotstandby controller, the system clock synchronization time tick precision and the control precision of the controller on the I / O card can be greatly improved, and convenience is provided for operationmaintenance and upgrading of a DCS of the thermal power plant.

Description

technical field [0001] The invention relates to the technical field of automatic control of thermal power plants, in particular to a controller cluster device applied to thermal power plants. Background technique [0002] Distributed Control System (DCS) of thermal power plant is a comprehensive product of computer, automatic control technology and network communication technology. It is based on the design idea of ​​control decentralization, risk decentralization, operation and management concentration, and adopts a multi-layer hierarchical, cooperative and autonomous structure, which adapts to the requirements of modern thermal power plant production and management. [0003] At present, the DCS system controllers of thermal power plants are all distributed in the cabinets of each control station. Each control station is equipped with a pair of redundant controllers, one master and one backup. / O card connection for data acquisition, measurement and output. Most of the co...
