摘要

如今，越南的电力系统将迅速发展高压直流系统，以响应国家的能源传输需求。HVDC点对点连接正在满足初步和最终设计的需求。对于越南电网系统，高压直流的程序，绝缘协调的基本要素，是必要的，并考虑瞬态过电压。通过数值模拟得到暂态过电压值。本文利用EMTP-ATP软件中的PSSE计算和传输进行参数化研究，模拟换流站内部最坏情况下的故障位置，使其具有最大的暂态过电压可能性。给出了越南电力系统的参数，并对MMC-HVDC模型进行了分析。研究结果为参与MMC-HVDC链路绝缘协调的工程师提供了见解。

Analyze the Transient Overvoltages in the station of Vietnamese model HVDC-MMC system

Nowadays, Vietnam's power system will develop an HVDC system quickly to respond to the national energy transmission demand. The HVDC point-to-point link is being met on demand for preliminary and final designs. For the Vietnamese grid system, the procedure for HVDC, essentials of insulation coordination, are necessary, and transient overvoltage is considered. Transient Over-voltages values are conducted by numerical simulation. Parametric studies using PSSE calculations and transfer in EMTP-ATP software are shown in this paper to simulate the worst-case fault locations inside the converter station to have the maximum value possibility of transient overvoltage. The parametric of the Vietnamese power system and the MMC-HVDC model are provided and analyzed. The results offer insights for engineers involved in the insulation coordination of the MMC-HVDC link.
