| Abstract | The purpose of transmission system planning is to determine the timing and type of new transmission facilities required in order to provide adequate transmission network capability to cope with the future generating capacity additions and load flow requirements. All the alternatives in transmission expansion planning should be evaluated carefully. Electric utilities always need to reduce the power losses and improve voltage profiles. To reduce the power losses and improve voltage profiles, utilities can install capacitor banks or add more substations to existing networks and they can also increase transmission voltage level. In planning, the utilities have to study the transmission networks looking into all possible alternatives and compare them by technical and economical criteria. The alternative, which meets the technical, economic and environmental criteria at minimum cost, should be selected. This thesis presents a study of transmission network expansion planning for Cambodian system. This study considers three options of transmission development and each configuration analytical studies of grid development staging requirements (four stages) in years 2000, 2005, 2010 and 2015 were carry out using technical economical parameters. The first option, is based on the development of a strong interconnection in the South of Cambodia to Vietnam at the 230 kV level and an interconnection is expected at the 115 kV level with Thailand in the north west of the country. In the second option, the additional peak generation is required and no interconnection is developed with international neighbors and the Cambodian load demand is internally supplied. The third option considers the development of hydro plant in the north of Cambodia and supplemented by the thermal generation in Phnom Penh. The main Phnom Penh grid has two separate interconnections with Vietnam and a small independent network is expected in the N01th West of the state comprising generation from a local hydro source and reliance on a Thai interconnection to supplement demand and energy deficit. In network analysis, PSS/E, load flow and contingency analysis software program has been used. The results of these alternatives have been obtained and the option 1 in transmission network expansion planning is recommended. The detailed power flow analysis has been carried out to assess the line loading voltage profile for different load and generation conditions. The requirement of reactive power compensation to contain the over-voltage in high voltage network under light load conditions, the effect of transformer tap changing has also been studied. |
