Manual Calculation

Distribution system is very important in the distribution of electric power to the load. Therefore, a good and efficient distribution system is needed. The underlying cause of poor electric power distribution system is the amount of voltage drop values in the existing system. In the electric power distribution, 20 kV medium-voltage and 380/220V low voltage networks are used. The distribution system of Gandum Feeder in Angke Substation uses medium-voltage network with Underground Cable channel. They are used because of the towering buildings and the dense population in the area. It is known that the longest the channel and the load current are, the greater the voltage drop. From the result of the voltage drop calculation of Feeder Gandum in Angke Substation, which uses manual calculation and ETAP 12.6.0 program, it showed a slight difference in the result. The result of the voltage drop obtained from manual calculation showed that the percentage value of voltage is 1,94%, while the result obtained from ETAP 12.6.0 program showed that the percentage value is 2,01% These results are still in the PLN standard, because it has not exceeded the specified standard that is -10% of its nominal voltage.

The Impact

Distribution system planning involves a set of complex analysis as the amount of data and associated parameters needed for the analysis are huge. Simplified reference network models (or a generic representative network) would help to reduce the amount of data to be handled, and thereby simplify the complexities of analysis. Depending on the parameters used, reference network models could be applied to assess the technical and economic performance of a network, such as, investment consequences against impact of customer end tariff pricing. The inherent idea is to develop a generic reference models that would help to visualize the impact of different planning parameters, such as adequacy, reliability, and quality against cost. These models have the potential capability for flexible usage on fast developing networks. This paper discusses an indigenous conceptual development of a reference network based on the Malaysian distribution system

Power Quality Conditioner

Background: The undesirable effect of power quality issues on distribution system due to power electronics based controllers; it is highly desired to design a novel power quality conditioner with a minimum number of switches. The proposed configuration reduces the switching loss and also effectively alleviates the power quality issues. This paper introduces the configuration of 3P4SW (Three Phase Four Switch) UPQC (Unified Power Quality Conditioner) for both shunt and series APF (Active Power Filter) as well as 3P9SW (Three Phase Nine Switch) UPQC topologies, which can be implemented in medium voltage power grid. The major challenge of phase balance with only four switches in UPQC is accomplished by adaptive Self-tuning PID using neuro-fuzzy logic control and adaptive reference current generation scheme. This controller improves sag and swells compensation with better angle control via shunt and series converter performance and passive components design. The efficacy of proposed topology is tested on MATLAB/Simulink software and results are compared with the existing three phase six switch configuration (3P6SW). Methods: The main objective of this work is to identify the most suitable configuration of UPQC to mitigate the power quality issues in power distribution system. to achieve this goal a Synchronous reference frame theory is used to generate the pulses in the back to back connected VSI in UPQC. Results: The suggested topologies should not compromise with the nominal functions of the controller; hence from the simulation analysis it clear that the 3P4SW UPQC, as well as 3P9SW UPQC topologies, will fulfill the given constraints and also it maintains the magnitude of the load voltage as per the standard values. Also, the THD percentage is maintained well within the IEEE standard. Thus the proposed topologies can be implemented for medium voltage distributed system with improved power quality.
