针对内蒙古电网与华北电网交直流混联格局下的工程建设时序问题，确定了内蒙古电网特高压交直流混联的目标网架结构，并构建了相应的数据模型。基于该模型提出多种特高压交直流建设时序方案。通过时域仿真对现状网架、目标网架及过渡期网架的安全稳定性进行了校核。针对过渡期部分站点短路电流超标以及直流外送通道发生严重故障后的切机问题，提出了相应的控制措施。并从潮流分布、短路电流和稳定性三个方面对各建设方案进行了对比分析，最后基于层次分析法围绕输电能力、潮流转移、短路电流、暂态稳定、动态稳定五个指标构建综合评价体系，通过权重分配、指标量化、得分计算实现方案最优排序，确定了对内蒙古电网最为有利的特高压交直流建设方案。
Abstract：Focusing on the construction sequence issues of power grid projects under the AC/DC hybrid interconnection pattern between the Western Inner Mongolia Power Grid and the North China Power Grid, this paper firstly determines the target grid structure of the UHV AC/DC hybrid interconnection system for the Inner Mongolia Power Grid and establishes a corresponding data model. Based on this model, multiple construction sequence schemes for UHV AC/DC systems are proposed. The safety and stability of the existing grid, target grid, and transitional grid are validated through time-domain simulation. For issues such as short-circuit current exceeding limits at certain substations and generator tripping following severe faults in the DC transmission channels during the transitional period, corresponding control measures are proposed. And a comparative analysis is conducted on various construction schemes from three aspects: power flow distribution, short- circuit current, and stability. Finally, based on the analytic hierarchy process(AHP), a comprehensive evaluation system is constructed around five indicators: transmission capacity, power flow transfer, short-circuit current, transient stability, and dynamic stability. Through weight assignment, index quantification, and score calculation, the optimal ranking of the schemes is achieved, and the most favorable UHV AC/DC construction scheme for the Inner Mongolia Power Grid is determined.
