Abstract

The invention discloses a simulation closed-loop test system and method for a power plant computer monitoring system. The system comprises a power system real-time simulation subsystem, a simulation interface card, a dispatching automation subsystem and the power plant computer monitoring subsystem. The power system real-time simulation subsystem is used for carrying out simulation calculation onthe power system according to the power generation control instruction to obtain a system simulation result of the power system. The simulation interface card is used for transmitting a system simulation result to the dispatching automation subsystem. The dispatching automation subsystem is used for making a power generation remote dispatching instruction according to the control target of the power system and the system simulation result. The power plant computer monitoring subsystem is used for making a power generation control instruction according to the power generation remote regulationinstruction. According to the invention, the simulation closed-loop test of the power plant computer monitoring system can be carried out, the operation of an actual power grid is not influenced, andthe safety is high.

Description

technical field [0001] The invention relates to the technical field of power system testing, in particular to a simulation closed-loop testing system and method for a computer monitoring system of a power plant. Background technique [0002] The power plant computer monitoring system is the equipment and device that uses digital electronic computer to monitor, control and adjust the power production process of the power plant. Among them, AGC and AVC are the most basic and important control and adjustment functions of the power plant computer monitoring system. [0003] At present, the test of computer monitoring system in power plant includes two parts: functional open-loop test and on-site closed-loop test. The on-site closed-loop test is to connect to the actual power grid for testing after on-site installation. It is characterized by complex procedures, especially involving dispatch authorization, and the test will directly affect the operation of the actual power grid a...
