A multi-port power router control system

Abstract

The present invention proposes a multi-port power router control system, including a three-layer structure, the first layer is the module controller part; the second layer is the port controller part; The upper computer and the integrated automation system are in a parallel relationship, each of which performs data interaction with each port controller through a network switch. A synchronous controller is set to ensure the overall synchronous operation of each port controller and each module controller; each port controller is interconnected by optical fiber to realize decentralized control of the system, which can effectively reduce data transmission delay and make control and protection more timely . By expanding the dedicated communication interface and synchronizing the clock, the synchronous interconnection of multiple power routers can be realized, and the capacity and reliability of the power router can be improved; by optimizing the power flow and quota of each port of multiple power routers, the system efficiency can be improved, and the cluster of power routers can be realized control.

Description

technical field [0001] The invention relates to the technical field of power electronic equipment, in particular to a multi-port power router control system. Background technique [0002] In recent years, the shortage of fossil energy and environmental pollution have become increasingly prominent, and the development of distributed renewable energy has become an important way to promote my country's energy transformation. With the increasing penetration of renewable energy power generation, the widespread popularization of distributed power generation, and the rapid increase in the proportion of generalized DC energy-consuming equipment represented by IT loads, inverter air conditioners, and electric vehicles, the scale of power transmission and distribution systems is increasing. Due to the limitations of the network structure, the traditional power system can no longer meet the demand, and the flexible interconnection and operation of the power grid will receive more and m...

AI Technical Summary

Problems solved by technology

The entire control process is cumbersome, and there is a large delay in the interaction of information between ports, which is prone to problems such as untimely protection and unsmooth control

[0006] (2) The master-slave control method is adopted, and the reliability is poor. If the upper computer fails or the communication between the upper computer and the port controller is interrupted, the system will not work, and may even cause serious accidents

[0007] (3) The integrated self-system cannot directly communicate with the port controller, and needs to pass through the upper computer node, which will cause the port control protection to be untimely

[0008] (4) It adopts the "1 drag 4" distributed architecture and master-slave control mode, which is not suitable for EER cluster control
