With the increasing importance of international society on the problems of energy safety, ecological environment, abnormal climate and the like, the reduction of fossil energy combustion and the acceleration of the development and utilization of renewable energy have become common consensus and consistent actions of countries in the world. At present, the basic trend of global energy transformation is to realize the transformation from a fossil energy system to a low-carbon energy system, and the final aim is to enter a sustainable energy era mainly based on renewable energy. In 2015, the newly increased installed capacity of global renewable energy power generation exceeds the newly increased installed capacity of conventional energy power generation for the first time, which indicates that the construction of a global power system is undergoing structural transformation. Wind power generation has been developed and applied in large scale worldwide as a technically mature, environmentally friendly renewable energy source.
The insulation problem of the wind driven generator is gradually highlighted while the wind power generation technology is rapidly developed. Compared with the traditional generator, the winding of the wind driven generator is impacted by pulse voltage with high frequency and rise time period, and the winding insulation bears more severe electric and thermal stress environment. When overvoltage exceeds the bearing capacity of motor insulation, partial discharge can occur inside the motor insulation, so that the insulation degradation time of the motor is greatly shortened, and finally, the insulation failure of the generator is caused. In recent years, a large number of wind driven generator insulation early failure phenomena appear, and the development of wind power generation technology is restricted to a certain extent. In addition, with the use of a large number of converters in onshore and offshore wind power generation, people pay more attention to the electrical insulation problem and the operational reliability of wind power generators and grid-connected equipment in a complex environment.
In order to prevent the failure of the wind driven generator caused by insulation aging due to partial discharge, the general practice of production departments is to enhance the inspection force of operation and maintenance personnel, judge whether the partial discharge of the variable frequency motor is abnormal or not by observing whether the external condition of the wind driven generator motor is normal or not, listening to the sound of the partial discharge, smelling the odor of ozone and the like, or stop the wind driven generator from operating. However, depending on the daily inspection of the operation maintenance personnel, the missed judgment and the erroneous judgment are easily caused. Especially for intermittent discharge, operation maintenance personnel are not easy to find in the patrol process, misjudgment is very easy to be carried out on the operation state of the variable frequency motor, potential safety hazards are buried, and a large amount of manpower and material resources are wasted when the operation maintenance personnel carry out daily patrol work.
