Abstract

The invention relates to the technical field of photovoltaic measurement and control, and discloses a distributed photovoltaic FTU measurement and control system and method, an acquisition module is connected with a photovoltaic device to be measured, and a protection module is connected with a logic judgment module; the acquisition module is used for acquiring voltage information, current information, power information and generating capacity information of the photovoltaic device to be detected, and sending the voltage information, the current information, the power information and the generating capacity information to the logic judgment module; the logic judgment module judges the voltage information, the current information, the power information and the generating capacity information to generate a control instruction, and sends the control instruction to the protection module; the protection module executes a protection action according to the control instruction; according to the invention, the problems of load fluctuation, electric energy quality reduction and line protection maloperation which are easily caused by confusion of existing photovoltaic management are solved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic measurement and control, in particular to a distributed photovoltaic FTU measurement and control system and a measurement and control method. Background technique [0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. Photovoltaic is a device that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation into electrical energy. It is a new type of power generation system. Environmental problems have increasingly become the biggest problem in the world. At present, photovoltaic power generation has the advantage of not producing carbon-containing waste gas that pollutes the atmosphere compared to thermal power generation that is currently used on a large scale. Therefore, in order to solve the increasingly serious environmental pollution, it is more ideal to use photovoltaic power generation instead of thermal power ...
