Mobile distributed photovoltaic power generation integrated test platform

Abstract

The invention discloses a mobile distributed photovoltaic power generation integrated test platform, including a cabinet body, a photovoltaic battery panel, a simulation platform and a storage battery, wherein the photovoltaic battery panel is arranged over the cabinet body, and converts the light energy into the direct current through the photovoltaic effect so as to provide energy for the simulation platform and the storage battery; the simulation platform is arranged inside the cabinet body, and the storage battery is arranged on the bottom of the cabinet; the simulation platform includes a bidirectional intelligent metering box, a simulation load, an inverter and a switch set, wherein the inverter is connected with the photovoltaic battery panel and converts the direct current to the alternating current for the use of the simulation load and a spot light load, the simulation load is connected to a simulation photovoltaic battery panel, and the inverter is connected to the bidirectional intelligent metering box through an inverter off-grid switch or an inverter on-grid switch so as to realize the private use and common use of the photovoltaic power generation. According to the invention, the accurate measurement of the on-grid and off-grid electric quantity, the prevention of the on-grid inverse power transmission and the clear on-grid breaking point can be realized, voltage-loss tripping during the maintenance and repair of lines is ensured, and the safety of the maintenance staff can be ensured.

Description

technical field [0001] The invention relates to a movable distributed photovoltaic power generation comprehensive test platform. Background technique [0002] With the increasing efforts of the country in energy conservation, emission reduction and environmental governance, the country vigorously advocates and promotes new energy projects, especially small-scale distributed solar power generation projects. There are also more and more residents and small industrial and commercial customers applying for distributed photovoltaic grid-connected projects. Among them, some apply for self-use, some apply for self-use of surplus electricity for online use, and some apply for all self-use. According to the different grid-connection needs of customers, speed up the grid-connection speed of distributed photovoltaic power generation projects, and actively solve the confusion and misunderstanding of the masses in distributed photovoltaic power generation. Complete grid connection serv...
