Abstract

A wind power generation system with maximum power tracking and a control method thereof are disclosed. The system includes a power generation module, a converter module, a control module and a detection module. The power generation module includes a wind generating set and a storage battery pack. The converter module includes an active power filter, a rectifier circuit, a chopper circuit, an inverter circuit and a three-phase filter. The control module includes an ARM processor, a storage battery controller, a trigger circuit and a maximum power tracking controller. The detection module comprises a signal acquisition circuit and an AD converter. According to the method, through measuring the fluctuation of harmonic wave and voltage, harmonic content in an electric network and a load and fluctuation and flickering of the voltage are reduced, and the harm of the harmonic wave to a power system and electric equipment is reduced. The converter module enables electric energy to be in the conversion of alternating current and direct current rapidly, a local direct current load demand is satisfied, and the quality of output electric energy is ensured. Three-gear maximum power tracking in different conditions is employed to enable the wind power generation system to be utilized most effectively, and the generating efficiency and the electric energy quality of obtained electric energy are increased.

Description

technical field [0001] The invention belongs to the field of new energy power generation and electrical technology, and in particular relates to a maximum power tracking wind power generation system and a control method thereof. Background technique [0002] In recent years, due to the obvious tightening of the supply and demand of coal, electricity and oil, my country's oil imports have increased day by day, and insufficient energy supply has become an important factor restricting my country's economic development. Traditional ore energy can no longer meet the needs of people's lives due to problems such as insufficient reserves and environmental pollution. In the long run, the development and utilization of new energy and renewable energy is one of the important measures to solve China's energy and energy environment problems, among which the utilization of wind energy is particularly important. Wind power is currently one of the power generation methods with the most mat...
