Problems solved by technology

The basic principle of photovoltaic power generation is the "photovoltaic effect", which is greatly affected by the intensity of light. The current photovoltaic power generation usually directly drives the electric motor, which often causes the frequent start of the electric motor. Moreover, the ability of photovoltaic power generation at night is limited. It causes the electrical equipment to stop working, seriously affecting the work efficiency, and switching the AC power supply manually is a waste of manpower and cannot accurately grasp the time

Abstract

The invention provides a photovoltaic transformer station monitoring system comprising a photovoltaic power generation output module, a GPRS communication module and a host computer, wherein the photovoltaic power generation output module comprises a photovoltaic control module, and an inverter module and a photovoltaic component module which are connected to the photovoltaic control module. The photovoltaic control module is connected to the GPRS communication module, and the GPRS communication module is connected to the host computer. The photovoltaic transformer station monitoring system eliminates the out-of-place inspection caused by the lack of responsibility and the low professional skill of a worker, and ensures the safe and reliable operation of an unattended transformer station.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic substations, and in particular relates to a photovoltaic substation monitoring system. Background technique [0002] In recent years, with the application and popularization of computer technology and Internet technology, more and more advanced technology applications have made the power industry develop greatly. Higher requirements are put forward for substation monitoring equipment and emergency maintenance, but the existing power grid dispatching automation monitoring equipment cannot adapt to the ever-changing needs, which is mainly manifested in: the previous power monitoring equipment mainly relied on LAN technology as the background management platform Provide information; in the existing power monitoring equipment, its power supply module is single. These shortcomings have caused great limitations to the expansion, monitoring and control of the grid. [0003] On the other hand, sola...
