The invention relates to an automatic power generation control step load disturbance test method for a thermal generator set. The method is mainly and technically characterized by comprising the following steps: setting rated power, an initial load value and a target load value of a thermal generator set, and entering an automatic power generation control mode; recording different moments of entering load change and actual loads at the moment according to an automatic power generation control step disturbance test load change curve; and checking whether the automatic power generation control speed regulation function under the step disturbance of the thermal generator set, the automatic power generation control response time under the step disturbance of the thermal generator set, the automatic power generation control dynamic deviation and the static deviation under the step disturbance of the thermal generator set are qualified or not. The design is reasonable, the test time is shortened, the risk of unit load fluctuation and equipment outage is reduced, the working efficiency is improved, and scientific guidance can be provided for an automatic power generation control test.
Description
technical field [0001] The technical field of thermal power generation of the present invention relates to a thermal power generation unit disturbance test, in particular to a thermal power generation unit automatic generation control step load disturbance test method. Background technique [0002] Automatic power generation control technology is a very important technology for generator sets. The control goal of automatic power generation control is to continuously reduce the regional load error due to load changes to zero, to balance the output of thermal power generation units with the grid load by the control center, to maintain the exchange power of the connection line in the region within the planned value range, and to reduce the regional operating cost. At the same time keep the grid frequency stable. In order to ensure the safe, reliable, high-quality and economical operation of the power grid, do a good job in the power control of the power grid tie line and assis...
