Wind turbine blade intelligent monitoring system for wind power station
Wind power station (for short: wind power station) is an application using wind energy into electric power, which belongs to green clean energy, is renewable, pollution-free, large energy, broad future an energy form, in line with the strategic policies and guidelines of our country "3060 double carbon". Wind power stations are usually set on the windward coast, the shallow sea area near the shore, and the windward flat or hilly land in the inland no-man's land. They all belong to the sparsely populated and harsh environment areas, and are easy to neglect their own equipment management and safety monitoring because of the rare human trace. For a long time, wind power stations have been using manual maintenance plan, that is, on-site routine maintenance after a certain period of operation. This maintenance method cannot fully and timely understand the operating status of equipment. However, due to insufficient preparation in advance, post-maintenance work takes too long and causes serious losses. The most important thing is to rely on human maintenance and lack of remote monitoring means, which brings hidden dangers to the safe operation of wind power station. Once failure occurs, it will cause huge economic losses and even pose a threat to personal safety.
The construction of wind power station is very complex, mainly composed of wind turbine, tower, energy storage equipment and power monitoring room or distribution room. In order to ensure the reliable operation of these components, and the status and environmental safety parameters of these equipment can be monitored in real time, the intelligent monitoring system of wind power station is a multifunctional online monitoring diagnosis and analysis system integrating signal acquisition, online monitoring and signal analysis, to carry out remote monitoring of the environmental conditions, energy storage equipment and safety conditions of wind power station. The vibration, temperature and electrical parameters of the wind turbine are monitored online, and the monitoring results are compared with the values set in advance. The online monitoring and diagnosis system can find the abnormal operation in time and give an alarm. The collected data can be analyzed and processed, so that the equipment fault can be accurately determined.
Ii. Program introduction
Intelligent monitoring system of wind power station adopts advanced multi-threading, network communication, automatic control, cross-platform browsing and other technologies to display, process and store the running state and operating parameters of each intelligent equipment, environmental state, security and fire status, and analyze and process the data between subsystems. Unified monitoring and management of subsystems or devices are implemented to ensure the security and stability of important devices in monitoring sites.
In view of the problems existing in the monitoring and operation of wind power stations, the main monitoring objects of the monitoring management system include: Wind turbine operation monitoring, wind turbine blade operation monitoring, wind turbine tower pole condition monitoring, power distribution equipment monitoring, energy storage equipment monitoring, outdoor environment monitoring, indoor environment monitoring, access control monitoring, video monitoring, fire monitoring, etc., so that operation and maintenance management personnel can timely and accurately understand and master the situation of wind power station. In order to ensure the safe operation of the wind power station, appropriate measures should be taken to control all kinds of situations.
