Abstract

The invention discloses a three-level voltage control system based on soft partitions, and belongs to the technical field of automatic voltage control systems. The three-level voltage control system based on soft partitions includes a tertiary control system, a secondary control system and a primary control system, the tertiary control system is connected with the secondary control system and controls the secondary control system, and the secondary control system is connected with the primary control system and controls the primary control system. The three-level voltage control system based on soft partitions solves the problem that division of an existing three-level voltage control mode control region is solidified in a hardware controller in the form of parameters, and continuous development of an electric power system and substantial change of a real-time operation condition are difficult to adapt to; and the three-level voltage control system based on soft partitioning has a stable and reliable power supply system, a long service life, high practicability, and a good using effect, and thus is convenient for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of automatic voltage control systems, in particular to a three-level voltage control system based on soft partitions. Background technique [0002] Automatic voltage control is an indispensable basic function for modern power system dispatching. The mainstream modes of automatic voltage control can be divided into three types according to the control level: [0003] The first is secondary control. The optimization calculation results of OPF are directly sent to the primary voltage controllers of each power plant for control. The typical representative is the German RWE power company. The main disadvantage of this control mode is that AVC is completely dependent on [0004] OPF has extremely high requirements on the data of the entire network. In addition, the response speed of AVC is not enough, and the dynamic control effect is not good. The second is the three-level voltage control based on hard partiti...
