| 摘 要： | 为提高大规模交直流系统实时数字仿真器(RTDS)建模的效率，提出了一套将各种常用机电暂态数据文件统一转换为RTDS模型的成套流程方法。对PSS/E-RSCAD数据转换时关键元件的模型对应关系及存在的问题进行了对比分析，从电力系统抽象建模、动态等值、数据预处理和数据转换等方面详细介绍了大规模交直流系统RTDS建模的关键技术。开发了一套常用机电暂态软件至RTDS的数据移植软件，并成功应用于浙江电网的RTDS快速建模研究。对称故障下的仿真结果表明，系统转换前后稳态和暂态特性相一致，验证了RTDS快速建模方法的有效性。

| Abstract: | In order to improve the efficiency of modeling large-scale AC/DC systems in RTDS(Real Time Digital Simulator),a set of method for converting various commonly used electromechanical transient data files into RTDS models is proposed. The model correspondence of key components is compared, the existing problems in PSS/E-RSCAD data conversion are analyzed, and the key technologies of modeling large-scale AC/DC system in RTDS are introduced in detail from the following aspects: abstract modeling of power system, dynamic equivalence, data preprocessing and data conversion. A set of data transplantation software from the commonly used electromechanical transient software to RTDS is developed and success-fully applied to the rapid RTDS modeling of Zhejiang Power Grid. Simulative results under symmetrical faults show that the steady-state and transient characteristics of the system are consistent before and after the conversion, which verifies the validity of the proposed rapid RTDS modeling method. |
