Description

Technical field [0001] The invention relates to a monitoring device for an intelligent distributed wind power generation system with adjustable voltage and power. Background technique [0002] The energy and environmental crisis has become an important issue affecting the sustainable development of human beings, and the utilization of clean and renewable energy is the fundamental way to solve this problem. With the maturity of wind power generation, photovoltaic power generation, wave power generation and other renewable energy power generation technologies, more and more renewable energy power generation systems are connected to the power grid in a distributed manner to meet people's daily production and living electricity needs. [0003] The power generation system based on wind power and photovoltaic power generation, as a supplement to the ultra-high voltage, long-distance, and large grid power supply mode, represents a new development direction of the power system. The...

Problems solved by technology

From the above analysis, it can be seen that in the existing wind power generation grid-connected configuration system, the utilization of wind energy can only take a small section in the middle. The waste, more importantly, wind turbines are frequently cut in and out of the power grid, which has a great impact on the power grid

This wind power grid-connected mode cannot realize continuous power transmission to the grid, and can only transmit power to the grid in a certain wind range
