Description

technical field [0001] The invention relates to the technical field of thermal power energy storage combined frequency modulation, in particular to a stable PCS group control device for thermal power energy storage combined frequency modulation. Background technique [0002] Frequency modulation is mainly to adjust the energy imbalance in a short period of time, so as to ensure the stability of the power grid. In my country, it mainly relies on traditional units, especially thermal power and hydropower for frequency modulation. In areas without hydropower, it mainly relies on thermal power and thermal power energy storage combined with frequency modulation technology. , using the joint operation of energy storage system and thermal power unit to form a new electric power frequency modulation power supply, which not only solves the shortcomings of traditional thermal power unit adjustment speed, delay of return and large error, but also makes up for the difficulty of energy sto...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a PCS group control device with good stability for combined thermal power storage and frequency modulation, which solves the problem that the partition board inside the existing device is fixed and it is difficult to adjust it according to the size of the installed equipment. position, it is easy to reduce the utilization of the internal space; the fixed partition is difficult to slide out, and it is time-consuming and laborious for the operator to install and repair the equipment, which affects work efficiency; it is difficult to replace the damaged area separately after the cabinet with an integral structure is damaged. Replacement greatly increases the cost of use
