Hydropower station power quick adjustment system and implementation method based on intensive small hydropower station groups

Abstract

Disclosed is a hydropower station power quick adjustment implementation method based on intensive small hydropower station groups. The hydropower station power quick adjustment implementation method based on the intensive small hydropower station groups aims at the practical problem that output fluctuation brings great impact to power grid operation after wind power integration, which is caused by the factors of being uncontrollable, unpredictable, strong in randomness and the like of wind power, and the characteristics of being small in unit capacity, large in quantity, rapid in start and stop, rapid in response adjustment and remote in geographic position of the intensive small hydropower station groups, stabilizes the wind power output fluctuation by rapidly adjusting power of the intensive small hydropower station groups, achieves joint optimization operation through complementation in aspects of the time, technical characteristics and the like of hydropower and the wind power, and meets the requirements for safe, stable and economic power grid operation from economical and technical performance. The hydropower station power quick adjustment implementation method based on the intensive small hydropower station groups achieves power quick adjustment based on the intensive small hydropower station groups for stabilizing the wind power output fluctuation from the aspects of adjustment autonomy and synergy of a device, a rapid start and stop adjustment characteristic of the small hydropower station groups, rapidity of the device and the like.

Description

Technical field [0001] The invention belongs to the technical field of industrial control, and in particular relates to a rapid power adjustment system and implementation method for a hydropower station that operates jointly with multiple energy sources such as wind, wind, water, and gas. Background technique [0002] my country is rich in hydropower resources. As a clean energy, hydropower has received strong support from the state. Although small hydropower has a small single unit capacity, it is numerous and dense in some areas. The single unit capacity of small hydropower is equivalent to that of wind turbines. Compared with other energy sources such as thermal power and wind power, Small hydropower has the technical characteristics of rapid start and stop. At present, the automation level of small hydropower stations is gradually improving, but there is a lack of rapid power adjustment on the side of hydropower stations. [0003] In recent years, with the continuous integratio...

Problems solved by technology

[0009] In order to realize the control of dense small hydropower groups according to the remote control strategy, it is necessary to establish a safe and low-investment remote optimization strategy control center telecontrol channel. The geographical location of small hydropower stations is extremely scattered and very remote. The composition of hydropower owners is diverse, and most of them do not currently have access conditions for power dispatching data networks. At the same time, the cost factors for channel construction must be realistic

At present, there is no overall solution in the market that considers the combined operation of dense small hydropower groups and multiple energy sources such as wind and gas, based on remote control strategy center + 3G wireless security channel + small hydropower station side configuration power integrated rapid adjustment control equipment
