Abstract

The application discloses a control method of a generator set and is applied to a power generation system. The power generation system comprises the generator set for generating output power, a generator set control system for controlling the generator set and an energy storage system for matching with the generator set in operation. The control method of the generator set is characterized in that the generator set control system determines whether the output power adjustment capacity which the energy storage system can provide can make up the deviation between the current output power of the generator set and the output power indicated in a power dispatch instruction when the energy storage system currently is in a state of matching with the generator set in operation and the operation state is normal, if so, the output power adjustment speed of the generator set is reduced, and if not, the output power adjustment speed of the generator set is improved. By means of the control method of the generator set, advantages of the generator set and the energy storage system are fully taken advantage of, the loss and abrasion of the generator set can be reduced, meanwhile, the response effects of the power dispatch instructions can be guaranteed, and the economy, stability and reliability of set operation can be improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for controlling a generating set. Background technique [0002] The power system includes the power grid, generators that provide power, and various electrical equipment. Automatic generation control (AGC) is a basic function in the dispatch automation system, which plays a vital role in ensuring the frequency quality of the power grid and the constant exchange power of tie lines. [0003] Due to the limitations of the traditional generator set's own characteristics, when responding to the AGC command of the power grid, it is usually necessary to change the control mode of the generator set to increase the output adjustment speed of the generator set and improve the response performance of the AGC command to meet the requirements of the grid dispatching for the generator set adjustment speed. requirements. For example, increase the output adjustment ...
