Abstract

The present invention discloses a balancing method of quantity of electricity when the electric network is electric-power shortage and its power system. Said invention method includes the following measures: regulating generating capacity of user's standby generating set of increase power supply, regulating tap position of transformer to reduce power consumption of electrical equipment and utilizing power frequency water pump in secondary water supply system to reduce power consumption to water pump so as to make the active power of power system be balanced and can prevent interruption of power supply.

Description

1. Technical field [0001] The invention belongs to the category of electric power supply, and relates to a power balance method and system, in particular to a power balance method and system capable of avoiding and reducing power pulling when the national power grid is short of power. 2. Background technology [0002] The power system includes three parts: power generation, power transmission, and power consumption. The electric energy generated by the generator is transmitted to the electrical equipment through the transmission line. In order to meet the needs of power consumption and voltage, and reduce the transmission of reactive current on the transmission line, the power grid A large number of large and medium-sized generating sets and transformers with adjustable voltage taps are installed, and a certain number of capacitors are installed; at the same time, some electricity users, such as high-rise buildings, shopping malls, hotels, factories, etc., in order to ensure ...
