A mobile distributed photovoltaic power generation comprehensive test platform

Abstract

The invention discloses a movable distributed photovoltaic power generation comprehensive test platform, which includes a cabinet body, a photovoltaic battery board, a simulation platform and a storage battery, wherein the photovoltaic battery board is arranged on the top of the cabinet body, and converts light energy through the photovoltaic effect into direct current to provide energy for the simulation platform and the battery. A simulation platform is set inside the cabinet, and the battery is set at the bottom of the cabinet; the simulation platform includes a two-way intelligent metering box, a simulation load, an inverter and a switch group. Among them, the inverter Connect photovoltaic panels to convert direct current into alternating current for use by simulated loads and spotlight loads, simulated loads are connected to simulated photovoltaic panels, and the inverter is connected to bidirectional smart metering through the inverter off-grid switch or the inverter grid-connected switch box to realize photovoltaic power generation for self-use and grid connection. The invention can realize the accurate metering of power on and off the grid, prevent grid-connected reverse power transmission, ensure that the grid-connected point has an obvious disconnection point, ensure voltage loss tripping during line maintenance, and ensure the safety of maintenance personnel.

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...
