中文摘要:
      指出了风资源的不确定性直接影响风电功率的稳定性,分析了传统风电机组通过电力电子装置与电网相连的矛盾,其谐波导致电力系统谐振,波形畸变,增加输电损耗, 危及电力系统的稳定运行; 同时, 传统风电机组系统支持能力有限,配置无功补偿装置,增加了系统成本,参与一次调频还有难度; 而且, 风电变流器复杂的结构是机 组故障率较高的部件,从而降低了风电机组的可靠性. 为解决上述问题,提出了以较低成本、 高可靠性、 较强的电网适应性为目标的各种新型风电机组技术,以满足风电大规模接入电网的友好性.
英文摘要:
      The uncertainty of wind is the direct impact on the stability of wind power output. Electric power systems have issues such as harmonic resonance, waveform distortion and increasing transmission loss caused by the electronic device on the traditional wind turbine connected with the grid. Wind converters become the high failure rate due to complicated components so that reducing the reliability of wind turbine. The traditional wind turbine system support ability is limited through the method of Static Var Compensator ( SVC) , so it is increasing system cost and it is difficultly for frequency adjustment. In order to solve the contradiction mentioned above, scholars aim at lower cost, high reliability and strong adaptability to explore a variety of new wind turbine technology for meeting the demand of large scale wind power connected to grid friendly.
