Abstract

The invention discloses a high-voltage alternating-current variable-pitch system based on an LTI driver, and belongs to the technical field of renewable clean energy. The high-voltage alternating-current variable-pitch system comprises a system safety chain, a main control unit, a main communication unit, a first sub-communication unit, a second sub-communication unit, a variable-pitch shaft control cabinet I, a variable-pitch shaft control cabinet II and a variable-pitch shaft control cabinet II, wherein a first LUST variable-pitch driver is arranged in the variable-pitch shaft control cabinet I, a second LUST variable-pitch driver is arranged in the variable-pitch shaft control cabinet II, and a third LUST variable-pitch driver is arranged in the variable-pitch shaft control cabinet III.The alternating-current variable-pitch control system can be widely applied to a high-power wind power generation system due to the factors that the motor size is small, the structure is simple, themaintenance is convenient, and the like. According to the high-voltage alternating-current variable-pitch system based on the LTI driver, the variable-pitch system adopts the LTI intelligent driver PM2+, and variable-pitch and safety control over each blade is completed by a special variable-pitch driving system.

Description

technical field [0001] The invention belongs to the technical field of renewable clean energy, and in particular relates to a high-voltage AC pitch system based on an LTI driver. Background technique [0002] Due to the decreasing fossil energy such as coal and oil in the world, all countries in the world have shifted their attention to the research, development and utilization of renewable clean energy, and wind power has become the focus of my country's new energy strategy. Wind power is the most developed in recent years. It is one of the green energies that are fast and capable of large-scale development and utilization. At present, wind turbines are constantly developing in the direction of large-scale, variable pitch and variable speed and constant frequency. [0003] The pitch control system is one of the core components of wind turbines. As the power of wind turbines continues to increase, an intelligent variable pitch control system integrating inverters, PLC contro...
