为了安全稳定地实现新能源电力的送出，内蒙古电网未来将建设多回“网对网”直流通道用于将清洁能源电力送至其他省区域电网，但在部分直流故障下，内蒙古电网仍存在暂态、动态稳定问题，需从规划层面对内蒙古电网主网架进行优化。在分析当前网架适应性的前提下，对比异步联网工程、内部加强工程和外部特高压延伸工程，分析不同工程可能出现的频率稳定、动态稳定以及短路电流问题，认为未来内蒙古电网与华北电网可采用异步联网或特高压交流联络网架，能够较好地满足直流通道接入需求。
Abstract：In order to achieve safe and stable transmission of new energy electricity, Inner Mongolia Power Grid will build multiple grid-to-grid DC channels to deliver clean energy electricity to other provincial and regional power grids in the future. However, Inner Mongolia Power Grid still faces transient and dynamic stability problems under some DC faults, which needs to be optimized from the planning level for the main grid structure of the Inner Mongolia Power Grid. Based on the analysis of the current network adaptability, this paper compares various technical routes, including asynchronous networking project, internal reinforcement project and external ultra-high voltage extension project, and analyzes the frequency stability, dynamic stability, and short-circuit current issues that may occur in different projects. Finally, this paper innovatively proposes that Inner Mongolia Power Grid and North China Power Grid should adopt asynchronous network or ultra-high voltage AC interconnection network to meet the needs of DC channel access.
