Power system restoration following a massive or complete blackout starts with energizing the primary restorative transmission system. During this primary restoration process, unexpected overvoltage may happen due to nonlinear interaction between the unloaded transformer and the transmission system. In the case of the Myanmar electric power system, there are so many wide outage experiences, including complete blackout cases, caused by 230kV line faults and so on. Consequently, Myanmar's system operators have been well trained to deal with wide blackouts. Howver, system blackout restoration has been conducted by relying on the experience of only a few specialists. So, more scientific analysis is required to meet the requirements necessary to ensure fast and reliable system restoration. This paper presents analytical results on the primary restorative transmission system of Myanmar, focusing on the problems during the early restoration process. Methodologies are presented that handle load pick-up, terminal voltage and the reactive capability limitation of black-start generators to compensate the Ferranti effect. Static and dynamic simulation with the PSSolution and EMTDC programs respectively for the six cases are performed in order to select the primary restorative transmission lines.

In the past, dramatic economical development of Korea could be achieved by well-organized 154kV power system network. Electric power Is a key Industry for the nation and industrial development. Nowadays we operates 345kV Power system with based transmission network and also we are operating 765kV power system to supply to the capital region. Currently developing countries in Southeast Asia are requiring the electric power technology to Korea so that they can acquire the source of the development-power system network. Therefore, it Is important to design transmission line and substation with appropriate methods. In this paper, a calculation and calculating process of shielding range using shield wires in Myanmar 500kV substation are reviewed according to the Myanmar 500kV power system project performed by the overseas projects section of the Korea Electric Power Corporation.

Recently, the principal processes of T/L design tend to computerize and therefore integrated T/L design system has been developed. Since, it makes the automatic selection of T/L route, tower position and optimum design possible, computerized design method is applied all over the world. KEPCO introduced Optimal PowerLINE for T/L design in Myanmar 500kV project that is as a part of overseas project. And as a result of that work, effective and economical design was carried out. This paper presents the comparative analysis between Previous method and Optimal PowerLINE method for investigating practical application to Myanmar 500kV T/L design.
