Abstract

The invention provides a distributed power flow control system and method, comprising: a distributed power flow controller, a main controller and an energy management module; the main controller is connected with the energy management module and the distributed power flow controller; the distributed power flow controller It is a distributed arrangement, set on the tension tower, used to collect the running data of the line and its own status information, and transmit it to the main controller; and execute the corresponding working mode according to the adjustment instructions; the main controller is based on the received adjustment target and preset. The set control strategy generates adjustment instructions and transmits them to the distributed power flow controller, and transmits the data uploaded by the distributed power flow controller to the energy management module; the energy management module dispatches according to the equipment status information sent by the main controller and the transmission line data. Plan, develop transmission line regulation targets and communicate to the master controller. The distributed power flow controller proposed by the present invention has high reliability, is easy to install and maintain, has the ability to prevent electromagnetic interference, and has a compact structure.

Description

technical field [0001] The invention relates to the technical field of power systems, and in particular to a distributed power flow control system and method. Background technique [0002] In a power system without any power flow control device, the power flow of the power grid is mainly distributed naturally according to the impedance function such as the system transmission line. Compared with the high impedance transmission line, the low impedance transmission line will bear a larger system power flow. However, this naturally formed uncontrolled power flow distribution is generally not the power flow distribution expected by the system operation, and may bring a series of problems such as insufficient transmission capacity, large transmission loss, over-voltage limit, and even damage to the system stability to the operation of the system. question. [0003] In order to improve the distribution of power flow in the system, the power system has mainly taken measures to bui...
