Method and system for controlling intelligent substation based on CRIO controllers

Abstract

The invention relates to a system and a method for controlling an intelligent substation based on CRIO controllers. The system comprises a station control system and a field system; the station control system comprises an operating terminal, a switch and a main central CRIO controller; the field system comprises a field CRIO controller and a primary device. The field CRIO controller is used for obtaining the data of the operating condition of the primary device, processing the data and transmitting the data to the main central CRIO controller via a network; the main central CRIO controller receives the data transmitted by the field CRIO controller and sends a control instruction to the field CRIO controller according to a preset program, and then the field CRIO controller controls the primary device; a substation operator can manually modify the control algorithmic logic of the main central CRIO controller at the operating terminal and manually send instructions to the main central CRIO controller. The method for controlling the intelligent substation based on the CRIO controllers is capable of realizing centralized management on the substation control algorithms and centralized monitoring on all devices and signals, and therefore, the reliability, flexibility and extendability of the intelligent substation can be improved.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a method and system for intelligent substation control based on a CRIO controller. Background technique [0002] The control of traditional substations often uses programmable logic controllers PLC (Programmable Logic Controller) and digital signal processors (DSP (Digital Signal Processor) dedicated controllers) to control on-site primary equipment. This kind of control device needs to lay signal and control cables separately for each primary equipment on site, which has poor reliability and poor scalability, and cannot realize centralized control of the entire substation. [0003] The intelligent substation control device developed on this basis combines the controller with the primary equipment, and transmits the collected parameters to the control layer through the communication standards such as IEC60870-5-103 / 104 through the network, or executes the instructions...
