The invention discloses a power distribution network voltage regulation and control system and method based on multi-compensation device coordination control. The system comprises a coordination controller, a dynamic compensation device, a reactive power compensation device and a voltage regulation device, wherein the coordination controller is in communication connection with the dynamic compensation device, the reactive power compensation device and the voltage regulation device, obtains line operation data collected by the dynamic compensation device, the reactive power compensation device and the voltage regulation device, distributes switching amounts for the coordination controller, the dynamic compensation device, the reactive power compensation device and the voltage regulation device participating in regulation, and outputs corresponding control instruction signals; the control instruction signal is used for adjusting the dynamic compensation device, the reactive compensation device and the voltage regulation device, and power distribution network voltage regulation and control based on multi-compensation device coordination control are achieved. Cooperative operation of various adjusting devices in the power distribution line is realized through the coordination controller, the power quality of the power distribution line is comprehensively improved, the problems of low voltage, large reactive power vacancy and the like in a power distribution area can be solved, and comprehensive improvement of the whole power transmission and distribution line is realized.
Description
technical field [0001] The present application relates to the technical field of power transmission and distribution regulation, in particular to a distribution network voltage regulation system and method based on coordinated control of multiple compensation devices. Background technique [0002] In recent years, with the development of the economy, the demand for electricity from users has been continuously increasing, and the load on the distribution network has increased dramatically. However, the distribution network generally has problems such as too long lines and too thin wire diameters, which lead to excessive line loss in the distribution network, and low terminal voltage and power factor, which seriously affect the normal power consumption of users. [0003] At present, the network loss and power quality problems of the distribution network are mainly improved from two aspects: the transformation of the distribution network and the change of the operating state of...
