摘要
提出一种新型的液压传导储能风力发电系统模型。该模型采用液压系统传导储能,有效改善风电波动性,降低风机的制造维护成本,并实现功率及电压控制。通过液压传导将发电机及相关控制系统降至地面,能够降低一定的风机制造成本。通过对该模型的分析和实验,证明该新型系统能适用于中小型风力发电系统并且可以有效克服现有风力发电系统的一些缺陷。液压储能实现异时发电并改善风电的波动性,而通过调节液压系统来进行稳压,则无需电力稳压系统。
A new model for wind power generation system based on hydraulic conduction and energy storage is put forward in this paper. The system adopted hydraulic conduction and energy storage to improve the fluctuation of the wind power system, which reduce the cost of manufacturing and maintenance and precisely control the power and output voltage of system. With the introduction of hydraulic system, the electricity generator and attached control devices could be set down onto the ground and therefore the cost of manufacturing will reduce correspondingly. Through the analysis and experiment of the present model, it is proved that this new system could be implemented in small and medium-sized wind power generation system, and effectively overcome some shortcomings of the cur- rent wind power generation system. The fluctuation of the wind power generation system is effectively improved through the hydraulic energy storage. The output voltage is stabilized by adjusting the hydraulic system and the voltage stabilization system is no necessary.
