02 十一 10 Power Electronics in wind and solar power generation system

Wind and solar power generation is a way to light and wind energy into electrical energy. Since solar and wind energy are highly complementary, wind generator and solar power systems make up an independent wind power and photovoltaic systems in resource intermittent imbalance, instability. According to the user’s electricity load and resource conditions for the rational allocation of system capacity. Scenery system can ensure the reliability of supply, but also reduce the cost of power generation systems. Meanwhile, wind and solar system is a separate distributed power supply system, do not rely on an independent power supply, do not consume electricity, without geographical restrictions, environmentally friendly and energy saving, but also as an elegant urban landscape by landscape position luster.
Wind and solar PV system consists of components (solar panels), wind turbine, battery, controller, inverter, several components. Wind and solar hybrid power system, power ratings for the wind power increases the peak power of photovoltaic cells, which together to the battery pack. Controller to control the wind power generator and photovoltaic maximize their performance, while also guaranteed not to overcharge the battery, can stabilize the voltage, the system is in constant voltage mode of operation. The system is no pollution, no noise, no waste, is a natural, clean renewable energy. To make the living environment of mankind no longer subject to pollution, wind and solar will be the inevitable choice for the world’s energy future. Currently, the use of solar and wind in different seasons, time, complementary characteristics of wind and solar power generation developed lighting technology, has been improving, and at an unprecedented speed and intensity rapidly across the country.
2 menstrual provincial approval in 2007, Johnson Electric Company of Henan Province, the source of wind power engineering research centers. Now outside the advancing Changge Xuchang Dong District 9 Road and State Road 107 different sections, development and installation of a wind turbines and solar street lighting system. Practice has proved that rational design to good effect.
Urban road lighting design based on standard cjj45-2006, Johnson Electric Company’s wind and solar sources street lighting system configuration, such as scheduled.
Power Electronics (pe) technology is the use of power electronic devices for power control and conversion of the subjects. It includes pe devices, converter circuits and control circuit of three parts, electricity, electronics, control between the three major areas of electrical engineering interdisciplinary. With the development of science and technology, pe technology and modern control theory because, materials science, electrical engineering, microelectronics and many other closely related fields, has gradually developed into an integrated multi-disciplinary nature of mutual penetration of technical disciplines, its application field is almost involved in various industrial sectors of national economy. There is no doubt that it will become the new century one of the key supporting technologies.
