The invention discloses a semi-physical object simulating platform of a power plant instrument control system based on thermal power generation and a control method. The semi-physical object simulating platform comprises a heater, a heat exchanger, an air pump, a turbine and a controller. The outlet of the heater is connected with the inlet of the heat exchanger through a pipeline. A temperature sensor is arranged on the pipeline between the heater and the heat exchanger. The outlet of the heat exchanger is connected with the inlet of the turbine through a pipeline. The outlet of the air pump is connected with the outlet of the heat exchanger through a pipeline. A flow meter and an electromagnetic valve are arranged on the pipeline between the outlet of the heat exchanger and the inlet of the turbine. The controller is connected with the temperature sensor, the flow meter and the electromagnetic valve through an I / O board card respectively. The controller automatically adjusts the flow of air supplied to the turbine and forms feedback so as to more vividly simulate the thermal power generation industrial process.
Description
technical field [0001] The invention relates to the technical field of power plant instrument control simulation, in particular to a semi-physical simulation platform and control method of a power plant instrument control system based on thermal power generation. Background technique [0002] Due to the particularity of the working environment of the power plant, it is impossible for university researchers to go deep into the front line of the power plant to conduct theoretical research on the power plant, so the necessity of building a semi-physical simulation platform has emerged. There are many types of power plants, such as thermal power plants, nuclear power plants, hydropower plants, wind power plants, etc., among which thermal power plants account for the vast majority. If a semi-physical simulation platform can be built, researchers in colleges and universities can use this platform to familiarize themselves with the process flow of the power plant, explore the contr...
