Problems solved by technology

However, it can be clearly seen that the monitoring system in this solution only monitors the real-time status of each device, so as to determine the fault through the main control system, and cannot achieve the control, monitoring, detection and reasonable energy management of the existing microgrid. There is no guarantee of stable operation in grid-connected and island modes

Abstract

The invention relates to a distributed generation microgrid system, in particular to a monitoring system applicable to different types of wind photovoltaic storage microgrid systems. The monitoring system comprises a communication conversion module, a communication bus, total communication conversion modules, a monitoring work station, a database server and a remote Web server, wherein the controller of each subsystem of the wind photovoltaic storage microgrid system is connected with different communication conversion modules in a one-to-one correspondence mode; the communication conversion modules are connected with the total communication conversion module through the communication bus; and the total communication conversion module is connected with the monitoring work station, the database server and the remote Web server. The monitoring system has the effects of controlling, monitoring and detecting a wind generating set, a diesel engine unit, a photovoltaic generating set, an energy storage device, a power distribution measuring and control device, a protective device and the like of the whole wind photovoltaic storage microgrid system, so that the microgrid system can stably operate under a grid mode and an island mode. The monitoring system can control each subsystem of the microgrid and detect the operation parameters of the microgrid.

Description

technical field [0001] The invention belongs to the technical field of distributed power generation micro-grid systems, and relates to a monitoring system applicable to different types of wind-solar-storage micro-grid systems. Background technique [0002] With the development of the national economy, the demand for electricity has grown rapidly, and the scale of the power grid has continued to expand. Distributed Generation (DG) can provide the unparalleled reliability and economy of the traditional power system, with less pollution, high reliability, The advantages of high energy utilization efficiency, and the flexible and decentralized characteristics of the distributed power supply are well adapted to the decentralized power demand and resource distribution, delaying the huge investment required for the upgrade of the transmission and distribution network, and it is a backup with the large power grid It also improves power supply reliability. Although distributed power...
