Intelligent monitoring system based on photovoltaic micro-grid

Abstract

The invention discloses an intelligent monitoring system based on a photovoltaic micro-grid. The intelligent monitoring system based on the photovoltaic micro-grid comprises at least one local controller and a central controller, wherein the local controller is used for having control over various local devices which are arranged in the photovoltaic micro-grid, are connected with the local controller and are applicable to different communication protocols, and sending information which is collected from the local devices in a classified mode, the local controller has the function of extending different communication protocols, and the central controller is used for receiving the information sent by the local controller through the Ethernet, and analyzing the information received from the local controller to carry out remote monitoring and fault diagnosis on the photovoltaic micro-grid. According to the intelligent monitoring system based on the photovoltaic micro-grid, due to the fact that the local controller which can extend various protocols, and the central controller are adopted, remote management and remote monitoring can be carried out on the local devices which use different communication protocols, an islanding system formed by various power stations can be avoided, and unified, complete and real-time monitoring of the photovoltaic micro-grid is achieved.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to an intelligent monitoring system based on a photovoltaic microgrid. Background technique [0002] In today's world, fossil energy sources such as coal and oil are frequently running out, and the problem of environmental pollution is becoming increasingly serious. As the most potential renewable energy, solar energy is more and more favored by people because of its unlimited reserves, universality of existence, cleanness of utilization and practical economy. Vigorously developing the photovoltaic industry and actively developing solar energy have received unprecedented attention worldwide, and have become an important part of the sustainable development strategies of various countries. Photovoltaic industry, also known as solar cell industry, is an industry that uses solar-grade semiconductor electronic devices to absorb solar radiation and convert it into electrical energy....

Problems solved by technology

[0005] However, the existing photovoltaic power station monitoring system is mainly provided by the inverter manufacturer with the equipment. It mainly starts from the inverter of the factory to monitor some parameters of the power station operation. It is difficult or impossible to directly control the operation status of the inverter, and it is also impossible to obtain The information and control of other equipment in the power station cannot meet the real-time monitoring requirements of the power grid dispatching system for the power station

In addition, large-scale power stations will use products from different manufacturers, and the products of these different manufacturers are not compatible with each other, resulting in "island" systems, unable to form a unified monitoring system
