Adjustment system, method and device for thermal power unit

Abstract

The invention provides an adjustment system, method and device for a thermal power unit. The system comprises a circulation cooling water device, a circulation cooling water supplement device and a circulation cooling water prediction device; the circulation cooling water prediction device inputs detected information of the circulation cooling water device into a prediction model to acquire a water supplement amount prediction value and sends the water supplement amount prediction value to the circulation cooling water supplement device, the circulation cooling water supplement device adjuststhe water supplement amount of the circulation cooling water device according to the received water supplement amount prediction value, and the circulation cooling water device controls a water resource to cool a steam turbine condenser in the thermal power unit. According to the adjustment system, the water supplement amount prediction value can be obtained through the circulation cooling water prediction device, the water supplement amount of the circulation cooling water device is adjusted according to the water supplement amount prediction value, the situation that the amount of supplemented water conveyed to the circulation cooling water device is too high or too low is avoided, the operation safety of the thermal power unit is improved, and the resource utilization rate is increased.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a thermal power unit regulation system, method and device. Background technique [0002] A thermal power unit is a facility that uses combustibles as fuel to produce electrical energy. The basic production process of a thermal power unit is as follows: firstly, when the fuel is burned, water is heated to generate steam, and the chemical energy of the fuel is converted into heat energy; secondly, the steam pressure drives the steam turbine to rotate, and the The thermal energy is converted into mechanical energy, and then the steam turbine turns the generator, which converts the mechanical energy into electrical energy. Therefore, steam turbines play a vital role in thermal power units. The function of the circulating cooling water device in the thermal power unit is to cool down the steam turbine condenser. Therefore, the circulating cooling water device is an im...

Problems solved by technology

However, the supplementary water volume of the circulating cooling water device will change with time and cannot be measured in real time, so that when the supplementary water volume of the circulating cooling water device is too much, there will be a waste of resources during the operation of the thermal power unit. When the amount of supplemented water is too small, it will cause damage to the equipment in the thermal power unit

Therefore, due to the variability and uncertainty of the water supply of the circulating cooling water device, the safety of the thermal power unit is low and the resource utilization rate is low
