Gaoya dianqi在线路上加装串联电抗器是抑制短路电流的有效措施，但同时也对断路器瞬态恢复过电压（TRV）产生显著影响，会影响断路器的正常开断，进而影响系统的安全稳定运行。文中结合中国现有500 kV超高压线路串联电抗器工程，利用电磁暂态仿真软件EMTP-RV研究了不同工况下串联电抗器接入对断路器TRV的影响。研究结果表明：接入的串联电抗器参数、位置对TRV有重要影响，串入的电感量越大，TRV电压上升率越低；安装位置越靠近断路器，TRV上升率越大；线路长度对TRV上升率影响较小，引起的变化幅度在5%以内 ...

Control and protection of distribution network with non-utility induction generators using EMTP-RV
, 2006 Dans ce mémoire, des questions associées à la simulation en régime transitoire et à l'intégration au réseau de distribution d'une génératrice asynchrone privée (« NUIG : Non-Utility Induction Génération ») sont étudiées. L'objectif de ce travail est de vérifier l'influence de différents facteurs tels le niveau et l'emplacement de la charge et de la ...

A link between EMTP-RV and FLUX3D for transformer energization studies
Electric Power Systems Research, 2009This paper presents a programmed link between the electromagnetic transients program EMTP-RV and the finite element field solver FLUX3D. The model created in FLUX3D is driven from simulation designs in EMTP-RV. The test cases presented in this paper demonstrate that the coupling method is numerically robust and with sufficient accuracy.

This paper presents the model of a Static Synchronous Series Compensator with the simulation package EMTP RV. The model uses a neutral point clamped (NPC) voltage source converter (VSC) to generate a high quality waveform. The model operation is verified with two types of controllers: Direct and Indirect to validate their mode of operation.
