Abstract

The invention, which belongs to the technical field of photovoltaic generating, provides a monitoring system of photovoltaic generation. The monitoring system comprises a measurement control device and a dispatching communication cabinet. An output terminal of the measurement control device is connected with one end of an ethernet fiber converter by a four-core single-mode fiber; and the other end of the ethernet fiber converter is connected with an input terminal of a switch. An output terminal of the switch is connected with a luminous power prediction cabinet and the dispatching communication cabinet. A monitoring host is also connected to the output terminal of the switch. Besides, a network printer and a time synchronization and setting device are also connected to the output terminal of the switch; and the output terminal of the switch is also connected with an integrated protection screen, a first switch cabinet, a second switch cabinet, and third switch cabinets. According to the invention, real-time monitoring of the data and state of the photovoltaic generating device operation can be realized; and continuous and high-efficiency operation of photovoltaic generation can be realized well.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a monitoring system for photovoltaic power generation. Background technique [0002] Photovoltaic power generation: According to the principle of photovoltaic effect, solar cells are used to directly convert sunlight energy into electrical energy. A solar photovoltaic power generation system in the prior art includes a solar battery module, a controller and an inverter. A solar cell module is made up of a number of solar cells connected in series, parallel and hermetically sealed. Relying on solar cell components and utilizing the electronic properties of semiconductor materials, when sunlight irradiates on the semiconductor PN junction, due to the strong built-in electrostatic field generated in the P-N junction barrier region, the unbalanced electrons in the barrier region are generated And holes or non-equilibrium electrons and holes that are generated ...
