Abstract

The invention discloses a thermal power generating unit load control method, device and system, and is used for solving the problem that the efficiency of adjusting the power supply load of a thermal power generating unit is low due to boiler delay hysteresis of the thermal power generating unit. The scheme comprises the following steps: acquiring a target load power value and a load parameter of the thermal power generating unit; determining a target adjustment power value according to a difference value between the target load power value and the actual power supply power value represented by the load parameter; generating a first adjusting instruction and a second adjusting instruction according to the condensation water throttling load parameter and the steam extraction throttling load parameter of the power value thermal power generating unit; and controlling the condensation water throttling load and the power value steam extraction throttling load of the power value thermal power generating unit according to the first power value adjusting instruction and the second power value adjusting instruction. According to the scheme, the condensed water throttling load and the steam extraction throttling load of the thermal power generating unit are adjusted through the instruction, the negative influence of boiler hysteresis on the adjusting efficiency is reduced, and the overall adjusting efficiency of the load of the thermal power generating unit is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a load control method, device and system for thermal power units. Background technique [0002] Clean energy, also known as green energy, refers to energy that does not emit pollutants and can be directly used for production and life, including nuclear energy and "renewable energy." Part of the clean energy can be converted into electricity and utilized through the grid. [0003] Clean energy that can be converted into electrical energy includes, for example, wind energy and solar energy. The efficiency of converting these clean energy sources into electrical energy may be related to various factors such as seasons, weather, temperature, and humidity, which makes the efficiency of converting electrical energy fluctuate greatly. [0004] In order to ensure stable power generation, thermal power units can be used to cooperate with the above-mentioned clean energy production, and t...
