In this paper, switching overvoltages analysis based on the statistical study approach according to IEC 6007 Insulation Co-ordination are analyzed for the energization of the connected 115 kV underground and submarine cables from Khanom power plant to Samui Island substation. Comparative analysis of protection schemes including metal oxide surge arresters and controlled switching are analyzed for...
Electrical insulators of the Provincial Electricity Authority (PEA) of medium system are mostly porcelain insulator types that consist of pin type, line post, and pin post insulators. The distribution lines will be polluted by industrial contaminants, salt fog or natural dust. Experience shows that pollution flashover is one of the main natural calamities harming and affecting the voltage stability...
Electrical insulators in 22kV distribution system of the Provincial Electricity Authority (PEA) are mostly porcelain insulator types that consists of suspension, pin type, line post, and pin post insulators. The distribution lines will be polluted by industrial contaminants, salt fog or natural dust. Experience shows that pollution flashover is one of the main natural calamities harming and affecting...
Distributed generations (DG) can be used to enhance power generation systems and improve distribution system efficiency. However, the installation of DG units at non-appropriate location and sizing can result in negative impacts such as an increasing in power losses and violations of system constraints. In this paper, a new DG allocation planning tool is developed for determining the optimal location...
Assessment of distributed generation (DG) is a complicated task and it is a primary importance step in designing and planning of DG installation in distribution systems. The installation of DG units at non-appropriate location and sizing can result in an increasing in power losses and violations of system constraints. In this paper, a new DG assessment tool is developed for studying and evaluating...
In this paper, particle swarm optimization (PSO) is proposed to determine the optimal allocation of multitype FACTS controllers to enhance power transfer capability of power transactions between source and sink areas in power systems. The particularly optimal allocation includes optimal types, locations, and parameter settings. Three types of FACTS controllers including unified power flow controller...
