Abstract

The invention discloses an automatic adjustment control method and system for a supercritical thermal power generation set. The method comprises that the time length T of an adjustment signal and themagnitude P of the adjustment amplitude are collected; according to preset correspondence between the signal characteristic of the adjustment signal and start of an energy storage module, start setting of the energy storage module corresponding to the signal characteristic to which the time length T and magnitude P of the adjustment amplitude belong is found; and the energy storage module is set and started according to the signal characteristic of the adjustment signal, and the energy storage module is controlled to adjust the system frequency. According to different time lengths of the dispatching signals and signal change adjusting amplitudes of a power dispatching department, different energy storage modules are combined flexibly, the dispatching requirement is met, and the whole hybrid energy storage system runs efficiently, safely and stably.

Description

technical field [0001] The invention relates to the technical field of automatic regulation and control of electric power systems, in particular to an automatic regulation and control method and system for supercritical thermal power generating sets. Background technique [0002] At present, due to the large-scale renewable energy access to the grid, the safe operation of the grid has encountered relatively large challenges. Large-capacity load fluctuations seriously affect the frequency stability of the power grid. In order to stabilize the frequency of the grid and ensure the safe operation of the grid, a large number of pumped storage power stations and gas-fired power stations with rapid response capabilities have been built. However, as the socio-economic regional differences are getting bigger and bigger, and the structural imbalance of the power grid is getting more and more serious, it is no longer possible to meet the frequency regulation needs of the power grid on...
