求翻译：可靠、高效的风力发电系统的研发己经成为新能源技术领域的热点。然而，因为风能具有不稳定性、能量密度低和随机性等特点，同时风电厂通常位于偏远地区甚至海上，自然条件比较恶劣，因此要求其控制系统必须能够实现自动化运行，并且要求控制系统有高可靠性。所以对风力发电机组尤其是大型风电机组的控制技术的深入研究就具有相当重要的意义。是什么意思？

Reliable, highly effective wind power generation system research and development oneself after becomes the new energy area of technology the hot spot.However, because the wind can have the instability, the energy density low and characteristics and so on randomness, usually is located the remote dis
