| Summary: | Every effort was made by the planners during the designing stage of a distribution network to ensure reliability and security of supply to the system. Due to the ever increasing electricity demand the network connecting to it tends to expand too. This phenomenon when allows to persist without proper control and monitoring will weakens the system. Adding this to other possible causes, such as equipment wear and tear, human and natural interference, the once carefully designed network now prone to failures. This paper will focus on the scenario and its consequences to the distribution system reliability and security. A study is carry out on an 11 kV distribution network in Tenaga Nasional Berhad (TNB) Kelang. Selection of the network or feeder for the study was based on the one that experienced the most number of outages due to system failures or breakdowns for 12 month period between September 1997 to August 1998. The first chapter will be the introduction and chapter two will provide general information on TNB 11 kV distribution system setup. The next chapter will focus on the profiles of the selected feeder under study. This will be followed by the system study on the feeder using Power System Simulation Advanced Distribution Engineering Productivity Tool (PSS/ADEPT) Version 1.0. The fifth chapter will be on physical onsite investigation of the feeder installations. Chapter six will provide discussion on findings gathered from the two previous chapters. The conclusion to the study will be in chapter seven which is the last chapter. |
