摘　　要：针对微电网的推广应用还面临着诸多技术难题的问题,将电力系统数字仿真与物理模拟各自的优点与不足结合起来,充分发挥各自优势便可形成数模综合仿真模型,该模型将在微电网技术研究中发挥重大的作用。数模综合仿真接口是数模综合仿真系统的核心部件,而接口算法的选取是数模综合仿真接口设计的基础。在总结现有算法的基础上重点分析了理想变压器模型的稳定性,提出加强稳定性的有效措施及不稳定情况的处理方案。最后,通过算例仿真验证了各措施的有效性。Aiming at technical problems in popularizing micro grid, advantages and disadvantages of digital simulation of power system and physical analogue are combined to exert their advantages to build digital-analogue integrated simulation model, which can play a great role in technical research of micro grid. Digital-analogue integrated simulation interface is the key part of digital-analogue integrated simulation system while the interface algorithm selection is the basis of designing digit- al-analogue integrated simulation interface. On the basis of summarizing current algorithms, the paper analyzes stability of the prefigured transformer and suggests measures for strengthening stability and processing plan for instability. Finally, ef- fectiveness of all the measures is verified by simulation on examples.
