- In this paper, we analyze of Myanmar’s electric power system in order to select the primary restorative transmission lines.
- This overvoltage has an effect on the dielectric strength of buses, transformers, and generators which are connected at the receiving end of the transmission line. System simulations are required to review the Ferranti effect and to select the appropriate primary restoration line from the transmission line lists between the black-start generators and the big capacity generator. The items below are studied from the system simulations.
- Since the generators in Myanmar are, for the most part, hydro generators or gas turbines which can start by themselves, it is not possible to select primary restorative transmission lines in general to supply cranking power for large generation plants. Therefore, this paper reports selecting primary restorative transmission lines which make reactive power cooperation between generators to control the system voltage rising due to charging the no-load long distance transmission lines. Lawpita H/P and Paunglaung H/P are selected as the black-start generators because they produce the most electric power and have the largest generation capacity.
- This paper investigated six cases of primary restorative transmission lines by static and dynamic simulation. PSSolution and EMTDC are used for static and dynamic simulation, respectively.
- EMTDC is used for dynamic simulation. Three Phase RMS voltage at the black-start plant and Phase RMS voltage at the priority participation plant are investigated with the results of the dynamic simulations. The results of the dynamic simulations are shown below.
