A photovoltaic power generation monitoring integrated device

Abstract

The invention relates to a photovoltaic power generation and supervisory control integrated device. A communication module receives information output by an intelligent device of a photovoltaic power generation electronic system, performs photoelectric conversion on the information and then uploads the information to a power station supervisory control system, or displays the received information through a man-machine interaction module; a DC (Direct Current) amount inputting and AC (Alternating Current) acquisition module acquires a DC amount and an AC amount output by the intelligent device of the photovoltaic power generation electronic system, performs A / D conversion on the DC amount and the AC amount, and displays through the man-machine interaction module; an input and output module isolates the contact between the outer input and output amount and a CPU (Central Processing Unit) module 1 to realize action of a relay or alarming; the man-machine interaction module displays parameters of the intelligent device of the photovoltaic power generation electronic system. The photovoltaic power generation and supervisory control integrated device integrates a communication manager, a photoelectric converter, a measurement and control protection device and a communication cabinet, so that the integrity is high, the volume is small and the investment is low; a communication management module and a photoelectric conversion module are arranged internally, so that intensive transmission and uploading of the communication information can be realized; the photovoltaic power generation and supervisory control integrated device can be connected to a current mainstream power station supervisory control system conveniently.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic power generation monitoring integrated device. Background technique [0002] At present, the global energy problem is becoming more and more serious, the traditional fuel energy is decreasing day by day, and the development and utilization of green and environmentally friendly energy is becoming more and more important. As a new type of renewable energy, photovoltaic power generation has the advantages of being safe, reliable, clean and non-polluting, and renewable. Governments of various countries have also introduced policies to support the photovoltaic industry. After a lot of research, most of the photovoltaic power generation monitoring devices currently on the market are separate devices for measurement and control, protection, communication, and photoelectric conversion. This not only increases the placement space, increases the transfe...
