Abstract

The invention relates to a reactive power hierarchical and adaptive control method which is used for a distribution network. By creating a reactive power hierarchical and adaptive subsystem for the distribution network, the method connects the subsystem, a management system of the distribution network and an automatic voltage control system of a main power grid to control an automatic monitoring terminal for low-voltage distribution transformation of the distribution network and a reactive power compensation integrated cabinet, thus forming an automatic management system for the distribution network which has reactive power hierarchical and adaptive function of the distribution network. The system has certain adaptability, can recognize change of environment and automatically correct control actions, achieves optimal or near optical control effect, realizes reactive power integrated allocation of the whole power network and has obvious energy-saving and consumption reducing effect.

Description

technical field [0001] The invention relates to a control method, in particular to a layered self-adaptive control method applied to a distribution network. Background technique [0002] At present, the reactive power control of the power grid cannot integrate various factors of the high-voltage main power grid and the medium-low voltage distribution network to perform precise compensation and control of reactive power and voltage. The main grid automatic voltage control system (AutomaticVoltage Control referred to as AVC) in operation only controls the reactive power compensation equipment and the transformer on-load tap changer of the main grid. However, the reactive power automatic compensation equipment of the distribution terminal of the distribution network only performs reactive power compensation control on the user side of the distribution network and a single distribution transformer, and fails to form an integration of reactive power and voltage between the main g...
