摘要
针对海洋平台微电网的特点,设计了海洋平台微电网电压稳定性评估方案,对海洋平台微电网电压稳定性问题进行了分析研究。以渤海地区某海洋平台微电网为例,综合应用特征值法和L指标法识别出了海洋平台微电网的电压薄弱节点,进而对系统的电压薄弱节点进行了静态电压稳定裕度的评估,分析了该系统的电压运行水平;最后根据该平台微电网搭建仿真模型,在考虑典型故障场景下进行了暂态电压稳定性分析,比较其时域仿真结果与静态评估结果,验证了方案的有效性。本文研究可为有效监测海洋平台微电网电压运行情况,提高电压的运行质量等方面提供一定的借鉴意义。
According to the characteristics of offshore platform micro-grids, an assessment program of offshore platform micro-grid voltage stability was developed to study the voltage stability. Taking the micro-grid in a Bohai offshore platform as an example, the eigenvalue computation and the L index method were combined to identify the voltage weak nodes. Then the static voltage stability margin of such nodes was evaluated, and the level of voltage stability of the system was obtained. Finally, transient voltage stability was analyzed in typical fault scenarios. Time domain simulation results and static assessment results were compared to verify the effectiveness of the program. The research here could provide some reference for the effective monitoring of micro grid operation of offshore platforms to improve the quality of voltage operation.
