Automatic dispatching system based on solar power generation

Abstract

The invention provides an automatic dispatching system based on solar power generation. The automatic dispatching system comprises a foundation platform, a monitoring module, a prediction module, a scheduling module and an analysis module, wherein the monitoring module comprises real-time irradiance, real-time voltage and real-time power monitors. A self-coupling transformer with an adjustable band or a VAR voltage changing device is arranged on the output side of an inverter, and the conversion of the sub-joint is realized through a closed-loop control system, so that the amplitude and the phase of the output voltage are completely controlled, and the output voltage waveform does not have a large range of fluctuation. Direct current voltage can be obtained through an uncontrollable dioderectifying circuit. The voltage can be controlled in a fraction of a second to automatically maintain the regulated power grid voltage level and the electric energy quality by changing the direct-current voltage by changing the direct-current voltage, which is particularly beneficial to a power grid with a weak system, and a relatively high power factor can be achieved. The safe operation after the new energy is input into the power grid is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation and dispatching equipment, in particular to a dispatching automation system based on solar power generation. Background technique [0002] In recent years, worldwide environmental pollution and energy shortages have forced people to work harder to find and develop new energy sources. New energy is a clean energy that protects the earth's ecological environment on which human beings depend, and it is bound to gradually replace the use of traditional energy. Among them, photovoltaic power generation has developed rapidly in the past ten years. It is a non-polluting and abundant energy source, and can generate power near the load center, so there is no need to erect high-voltage transmission lines across the city. In many countries, the government's policy support and consumers' preference for green electricity have led to the rapid expansion of the photovoltaic energy market. ...
