Abstract

The invention discloses an automatic flexible load control system based on grid frequency. The system comprises a grid frequency collection module, a DSP controller and a control output module, wherein the control output module comprises a flexible load controller and a wireless signal transmitting module; the flexible load controller is used for controlling on and off of a socket; the wireless signal transmitting module is used for regulating and controlling a power load with a wireless control function. The invention also discloses a control method of the automatic flexible load control system based on grid frequency. The method is capable of regulating the electricity utilization power of the electric load according to the real-time power supply frequency of a grid or deciding whether to cut off a power supply of the electric load. The system is capable of realizing flexible and fine automatic power load control, obviously improving the frequency regulation and control capacity of the grid and ensuring the grid elasticity resuming performance under serious failure situations such as ultrahigh voltage direct current bipolar block, and is applicable to flexible automatic control on household electric appliances.

Description

technical field [0001] The invention relates to a grid frequency-based flexible load autonomous control system, and also relates to a control method of the grid frequency-based flexible load autonomous control system, which belongs to the technical field of power systems. Background technique [0002] After transforming from a self-sufficient regional power grid to a large-scale receiving power grid, the operating characteristics of the power grid will undergo fundamental changes and face many new technical problems, especially the cross-regional AC and DC power transmission channels due to equipment, external failures, disasters, failures, etc. The risk of outage due to reasons such as blockage, especially the sudden outage during the period of high-power transmission, will directly cause a greater impact on the safe and stable operation of the large receiving end power grid. How to effectively and quickly adjust the load when the UHV AC-DC transmission channel is out of se...
