A PCS group control device with good stability for combined thermal power storage and frequency modulation

Abstract

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. The technical problem to be solved by the present invention is that it is difficult to adjust the position of the partition plate, the space utilization rate is low, the partition plate is difficult to slide out, installation and maintenance are troublesome, affecting work efficiency, it is difficult to replace the damaged area alone, and the use cost is increased. In order to solve the problems of the above-mentioned technologies, the present invention provides a PCS group control device with good stability for combined thermal power storage and frequency modulation. The present invention is composed of a vertical adjustment mechanism and a horizontal adjustment device. The position adjustment ensures the space utilization rate, and the reasonable space distribution has better safety. The partition board can slide out, which is convenient for the operator to install and repair the equipment, and improves the work efficiency. The partition board can be easily disassembled and assembled. It can be replaced separately after damage, which reduces the cost of use.

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...
