The advantage of the technique in the computation of ATC is that it has the ability to reduce the time consuming AC power flow computations. The cubic-spline interpolation technique traces the curves of voltage magnitude and power flow variations with respect to the increase of real power transfer. ATC is then determined at the point where the voltage or power flow limits intersect the curves. The effectiveness of the proposed method is verified by illustrating the ATC evaluation on a practical test system. ATC results obtained from the proposed cubic-spline interpolation technique prove that the method is satisfactorily accurate and it is faster than the ATC method using the recursive AC power flow computations.","PeriodicalId":375856,"journal":{"name":"PECon 2004.

An accurate model of the USSC is developed aimed at examining its capability in mitigating power quality problems in a power distribution network. The USSC simulation model comprises of two 12-pulse inverters which are connected in series and in shunt to the system. A generalized sinusoidal pulse width modulation (SPVVM) switching technique is developed in the proposed controller design for fast control action of the USSC. Simulations were carried out using the PSCAD/EMTDC electromagnetic transient program to validate the performance of the USSC model. Simulation results verify the capabilities of the USSC in performing voltage sag compensation, flicker reduction, voltage unbalance mitigation, power flow control and harmonics elimination.","PeriodicalId":375856,"journal":{"name":"PECon 2004.

By August 2002, out of 82,000 EB installed nationwide, 53% became faulty. In some cases, the EB were found to be defective within days of being installed. It was suspected that the EB became faulty due to either vibration, shock or bump experienced during the transportation and handling of the EB, direct or indirect lightning strikes on the street lanterns or possibly inadequate design. A research project was undertaken by TNB Research Sdn Bhd (TNBR) to investigate the root causes of EB failures and to recommend improvements to the EB design. Samples of EB were obtained from the TNB vendors and from several sites around the country. The samples were subjected to various type tests and post-mortem analysis involving electrical and thermography tests. This paper presents the results of the tests performed and the recommendations made to TNB.","PeriodicalId":375856,"journal":{"name":"PECon 2004. Proceedings.
