Popis: The Vietnamese power system is growing rapidly both in terms of scale and complexity. Three links with China network in three independent areas with the Vietnam network. This chapter presents a study interconnection possibility between the Vietnam network and the China network by asynchronous back to back high voltage direct current links (B2B HVDC). Firstly, the analysis and the evaluation of the necessity of the B2B HVDC are investigated. Then the simulations are performed in EMTP-RV to identify technical constrains and benefits for two links. Voltage Source Converter (VSC)—Modular Multilevel Converter (MMC) and Line Control Converter (LCC) are used to study. Several scenarios are studied such as voltage control, active and reactive control in normal operation and fault conditions. Finally, a comparison of two technologies (VSC, LCC) is carried out and recommendations are given.
