Centralized electric energy router control protection device

Abstract

The invention discloses a centralized electric energy router control protection device, which comprises a control host and a plurality of module main control board groups in communication connection with the control host, a main control plug-in is arranged on the control host corresponding to the module main control board groups, and the module main control board groups and the control host are synchronized through a synchronous plug-in signal. One control host is provided with a plurality of main control plug-ins, each main control plug-in corresponds to one port, and information interaction among different ports is realized through the main control plug-ins. Moreover, due to the existence of the plurality of main control plug-ins, and the signal synchronization between the main control plug-ins and the module main control board group, the timeliness of information interaction is improved.

Description

technical field [0001] The present application relates to the technical field of energy interconnection, in particular to a centralized electric energy router control and protection device. Background technique [0002] With the introduction of the concept of Energy Internet and the popularization and application of smart grid-related technologies, the proportion of renewable distributed energy such as wind energy and photovoltaics in the power grid will increase greatly, and the scale of transmission and distribution networks will also increase accordingly. The structure can no longer meet the demand, and the flexible interconnection and operation of the power grid will receive more and more attention. The power router has emerged as the times require. As a power electronic conversion device for the flexible interconnection of the power system, it has multi-port, multi-flow, multi-cascade Features such as function and shape. [0003] The multi-port power router based on th...

Problems solved by technology

[0004] The above control method has the following problems: 1) Each port is equipped with a controller, which increases the volume of the control room and increases the control cost; 2) The port controllers cannot perform information interaction, and each port transmits its own status to the host computer. The host computer determines the next step of the port according to the status of each port. There is a large delay in information exchange, and there may be problems such as untimely control and unsmooth actions.
