Auxiliary service device and method for mobile communication low-delay distributed power system

Abstract

The invention relates to an auxiliary service device and method for a mobile communication low-delay distributed power system, which comprises at least one unloading service client provided with a frequency detector, at least one communication interface control center and at least one load unloading control station, when the frequency of the alternating-current power grid power supply drops to a preset tolerable low-frequency value, at least one unloading control command is sent out through at least one mobile communication network by means of the communication interface, and each load unloading control station is respectively linked with and controls the power supply and power failure of a local feeder power grid of at least one electricity utilization load. Each load unloading control station is provided with at least one mobile communication module and a standby power supply device, so as to receive an unloading control command sent by the control center through the mobile communication module and carry out real-time and low-delay local feeder grid power supply power-off unloading on the link electricity load, and the standby power supply device provides a standby power supply for the electric load.

Description

technical field [0001] The present invention relates to a mobile communication low-delay distributed power system auxiliary service device and method. A frequency detector in a control center and a mobile communication network are used to control at least one load unloading control station of at least one remote unloading service client. A device and method for automatically and rapidly unloading at least one electric load in a state of low power frequency. Background technique [0002] When the existing power system is in normal operation, the power supply and load must be balanced. If the power load capacity is higher than the power supply capacity of the mains power supply, the frequency of the power system will drop, and in severe cases, it will endanger the stability and safety of the power grid. There are many feasible methods for the frequency to decrease unexpectedly. One of the traditional methods is to install an under-frequency protection relay, perform unloading ...

AI Technical Summary

Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art, and provide a mobile communication low-delay distributed power system auxiliary service device and method, which can eliminate the above-mentioned existing power low-frequency unloading system and various patents. All easy-to-generate clients need to be equipped with low-frequency detection equipment, which increases the cost of the equipment sharply and is not suitable for the active unloading control of clients, making the unloading control more complicated, higher equipment costs and unexpected large unloading Problems and Disadvantages of Regional Blackouts
