风力发电机组自耗电的控制优化

Reduce the Power Consumption of Wind Turbine

随着风力发电行业的持续发展,海上风电和陆上风电的上网电价持续降低,开发商对于风电机组的度电成本要求越来越高。海上风电开发成本高,投资风险大,对于风电机组的发电量和自耗电要求也更高。在保证风力发电机组安全稳定工作的基础上,以风力发电机组主要耗电设备工作特性为主要出发点,利用自适应、间歇、关联性控制等技术优化辅助供电系统设备的控制策略。优化风力发电机组主要耗电设备控制策略是在不增加硬件成本的基础上降低机组自耗电,既可以增加上网电量,也可以减少下网电量,有利于风电场提高投资收益,提高机组性价比。

With the sustained development of wind power industry,the price of offshore wind power and onshore wind power on the grid continues to decrease,and developers are increasingly demanding the cost of power for wind turbines.Because of a large amount of investment capital and high investment risk,the offshore wind power pursues higher power generation and less self-consumption of wind turbines.Based on the principle of safe and stable operation of wind turbines,and taking the working characteristics of the main power consuming equipment of wind turbines as the main starting point,the control strategies of auxiliary power supply system equipment are optimized by using adaptive,intermittent and correlation control technologies.Optimizing the control strategy of the main power-consuming equipment of wind turbines and reducing the self-consumption of wind turbines on the basis of not increasing the hardware cost can not only increase the amount of on-grid energy,but also reduce the amount of off-grid energy,which is conducive to increasing the investment income of wind farms and improving the performance-price ratio of wind turbines.
