As technology advances, the development of wind power generators industry, the introduction of fans but also from imported equipment, the development of the now own design and production of domestic fans. With the increase of fan types and quantities of the new units continue to put into operation, the old unitĄŻs aging fanĄŻs daily operation and maintenance is more important. Now make a few fans of the operation and maintenance. Wind turbine control system is controlled by the microprocessor industry, generally by the number of CPU parallel, strong anti-jamming capability of its own, and connected to a computer through communication lines, can be remote controlled, which greatly reduces the run workload. Run the fan work is so remote troubleshooting, and operating data for statistical analysis and Failure Analysis. Most remote troubleshooting fan failures can be controlled remotely reset and automatic reset control. Fan operation and power quality is closely related to good or bad, to a two-way protection, fans set up a multi-fault protection, such as the grid high voltage, low power high frequency, low status, these faults are automatically reset. Because wind energy can not be controlled, so the wind speed over the limit can also be automatically wind generator reset. There are temperature limits can be automatically reset, such as the high generator temperature, gearbox temperature, high, low, low ambient temperature. Overload the fan failure is automatically reset. In addition to automatically reset the fault, other faults can be caused by a remote reset control following reasons: (1) fan controller failure false; (2) the detection sensor malfunction; (3) controller that the fan does not run reliably. . Statistical analysis of operating data in the operation of wind farm equipment happens to detailed statistical analysis of wind farm management is an important part. By running the statistical analysis, operation and maintenance work on the quantitative assessment, but also on the wind farm design, wind resource assessment, selection of equipment to provide an effective theoretical basis. Monthly statistical report generation is an important part of running the work, its true reliability and economic benefits directly linked. Its main contents are: the fan on power generation, electricity market, fans of the equipment during normal working hours, down time, the standard use of hours, power outage, the failure time. Fan power curve statistics and analysis, can increase output and improve the fan in the utilization of wind energy to provide practical basis. For example, in the domestic small wind turbine power curve analysis, we have three fans, after the installation of angle were adjusted to reduce the high wind speed areas and efforts to improve the utilization of low wind speed areas, reducing failures and power had made The high temperature failures, improve equipment availability. Data on wind conditions through statistical analysis, we have mastered the various types of fan output rule changes with the seasons, and this may make a reasonable schedule of regular maintenance work to reduce the wind resource waste. . Failure Analysis of fans through our in-depth analysis of various faults, can reduce troubleshooting time and prevent the occurrence of multiple failures, reduce downtime, increase equipment availability, and availability. Such as the 150kW wind turbine yaw motor overload of the failure of the analysis, we have the following number of reasons that caused the failure occurred, the first machine on the motor output shaft and the key block wear lead to overload, yaw gap Slipper overload caused by the change, broken teeth tooth plate large yaw yaw motor overload occurs, the electrical overload on the reasons causing partial damage to the module soft, soft side trigger plate is damaged, wind turbines damaged contacts yaw, yaw electromagnetic brake work is not normal and so on. In another example, in the Jacobs family lost fan control voltage failure analysis, we used exclusion test method, the security chain which may cause the failure of the measuring signal components with wiring for signal relay and short circuit transformation, the final cause of the fault localization in too fast on the pressure switch setting, the failure occurred less often, improve equipment utilization, reducing the number of replacement brake pads to reduce operating costs.
