Intelligent backup power load control method and system

Abstract

The invention relates to the technical field of power supply equipment and discloses an intelligent generator set load control method and an intelligent generator set load control system. The method comprises the following steps of: monitoring the condition of a generator set in real time and generating control strategy signals according to the condition; converting the control strategy signals into switch control signals; controlling the state of switches and the interface voltage of a storage battery according to the switch control signals to realize charge-discharge control of the storage battery. Through the technical scheme provided by the invention, intelligent charge-discharge adjustment of the storage battery is achieved, the charge-discharge mode of the storage battery can be adjusted dynamically according to the load condition of the generator set to fully utilize the commercial power resource, the condition of overload working of the generator set can be relieved, and the resource service efficiency is improved under the premise of guaranteeing the operation reliability.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to an intelligent backup power supply load control method and system. Background technique [0002] In the core communication network nodes, in order to ensure the safety and stability of the entire communication network, it is necessary to ensure that the communication system can continue to operate normally when emergencies such as power outages occur, until the normal power supply is restored. For a long time, generator sets have been widely used as backup power for communication systems. When a generator set is used for backup power supply, an appropriate generator set should be selected according to the load of the communication system. In addition, in order to further ensure the stability and continuity of power supply, a battery pack is usually used as a backup power supply when the generator set is arranged. Replenish. [0003] In the traditional design, the...

[0004] However, in reality, the existing method makes the one-time design capacity of the generator set in the backup power supply too large, especially for the core computer room with a long backup time and a large capacity of the battery pack, it is necessary to use a generator set with a very large capacity

According to the survey, the current mains power supply is basically stable, especially in the core computer room in the city center, the number of power outages is relatively small, the duration of power outages is relatively short, and the number of actual use of generator sets is very small. Using the existing method will not only increase the investment in equipment purchase In addition, the area of ​​the oil machine room is increased, the use efficiency is low, and the waste of resources is serious

However, if you want to carry out effective dynamic planning on the basis of the existing methods, the existing simple connection and control methods are difficult to achieve flexible configuration
