大规模风电接入电网的相关问题及措施

Problems and Measures of Power Grid Accommodating Large Scale Wind Power

大规模风电的开发利用是我国在新时期做出的一项重要战略选择。针对目前我国大规模风电接入电网的相关问题,借鉴国外先进经验展开论述。指出我国风电大规模、集中开发、远距离、高电压输送的独有特点,以及由此带来的系统调频、调峰、风电功率预测、低电压穿越等运行控制问题。在政策法规、并网导则和检测认证等方面与国外进行比较,指出了存在的问题。最后提出了大规模风电接入电网的相关措施。

Large scale wind power development is an important strategic choice in China＇s new era. Aiming at problems which were brought by wind power integration, comparison was made with the foreign experience. It was pointed out that, the wind power in China had some distinct characteristics such as large scale, centralized development, long-distance and high voltage transportation, which resulted in some problems in operation and control, i.e. system frequency regulation, peak regulation, wind power prediction and LVRT （low voltage ride-trough） and so on. Then some comparisons in policy, wind power integration requirement, test and certification were made, and the existing problems were pointed out. In the end some relevant measures against large scale wind power integration were put forward.
