摘要:

目前特高压直流输电控制保护系统的仿真模型主要是基于典型的控制保护结构进行构建，难以准确地模拟实际特高压直流输电特性，且商业仿真软件大多提供封装式模块，难以根据实际情况进行修改和自定义建模。因此有必要搭建开放式特高压直流输电控制保护模型，以便准确地模拟实际特高压直流输电工程的控制保护特性。ADPSS可实现交直流机电暂态与电磁暂态混合仿真，在解决交直流混联电网建模问题上具备独有的优越性。在ADPSS平台上搭建了基于实际特高压直流输电工程的开放式控制保护系统，包括完整的换流器控制系统、换相失败预测控制与换相失败保护等。通过对比实际工程实验和所搭建的仿真模型在控制指令阶跃响应仿真与逆变侧交流系统故障仿真下的结果，验证了基于ADPSS的控制保护系统模型的准确性和有效性。

Abstract:

At present, the simulation models of UHVDC transmission control and protection system are mainly based on typical control and protection structures, which makes it hard to simulate actual UHVDC transmission characteristics. Besides, most commercial simulation softwares provide encapsulated modules, which are difficult to modify and customize modeling according to the actual situation. For the reasons above, it is of vital importance to establish an open-style UHVDC transmission control and protection model to simulate the characteristics of actual UHVDC transmission projects. ADPSS has unique advantages in modelling AC/DC hybrid power grid because it can realize hybrid electromagnetic and electromechanical transient simulation of large-scale AC/DC power system. Using ADPSS, it builds an open-style UHVDC transmission control and protection system based on practical projects, including converter control, the commutation failure prevention and the commutation failure protection. The accuracy and effectiveness of the model are verified by comparing the outputs of control instruction step response simulation and inverter side AC fault simulation with the same measurements of practical experiment. This work is supported by National Key Research and Development Program of China (No. 2016YFB0900800).
