Abstract

Power flow analysis is used to determine the power flow parameters that are useful for planning the system to operate optimally as well as changes to existing systems, such as what happened at PT. Sele Raya Merangin Dua, which is currently making system changes in the form of additional loads. With the addition of this load, it is necessary to conduct a power flow analysis to determine the effect of increasing the load with the aim of knowing the system performance so that it can be in optimal condition. The research method used is qualitative-descriptive which is carried out in a simulation using ETAP 12.6 software where the results of the simulation will be tabulated and graphed. The results showed that the increase in load caused an increase in power generation and power distribution, especially on swing-buses to load-buses and branch buses. From the previous generation power of 1069.1 kVA increased to 1155.2 kVA but did not affect the performance of each power system equipment PT. SRMD and the electric power system are still in optimal condition.

Abstract

Palm oil is one of the choices of growth companies in Indonesia as biomass energy. Biomass is organic matter made from plants and animals that contain energy. The result of the palm oil processing process is liquid and solid waste.Liquid waste in the form of sludge can be reprocessed into pure palm oil with several treatments.Solid waste in the form of shells and fibers (fibre) derived from palm pulp is used as fuel in boilers and used as steam steam for the process of generating electricity through turbines. Research on the utilization of solid palm oil waste fibers and shells was carried out at PT. Nusantara Plantation VI PKS Bunut because of its large waste potential as an alternative fuel source (renewable energy. Processing capacity of the plant of 30 tons of FFB/hour produces 3.9 tons of fiber solid waste and 2.1 tons of shells, the total solid waste as fuel is 6 tons/hour. The fuel requirement of the plant is 4.55 tons/hour so that there is a difference of 1.45 tons/hour. The electrical energy generated from the utilization of 6 tons/hour of fuel is 776 kW/Hour, while the realization energy used by the factory is 750 kWh/Hour.There is an excess energy of 2.6 kW/hour. This indicates that the use of shells and fibers as fuel for new and renewable energy at the PLTU PKS Bunut PT. Nusantara VI plantations are very good.

Abstract

The continuity of electrical energy requires an electric energy management with high efficiency and easy-to-obtain fuel. One of them is the Ombilin Steam Power Plant (PLTU) with a capacity of 2 x 100 MW. At ombilin power plant there is a system of its own use that is obtained from the generator when the plant is operating. In this study, contingency analysis was conducted on its own system simulated using ETAP 12.6 software. Contingency analysis is the study of the safety of an electric power system by conducting a power flow analysis of the impact of a number of contingency cases such as the release of one or more generators and the release of one of the tramsmission elements. With contingency analysis, an electric power system will be able to calculate the disruption that occurs for example in the use of a power plant unit, so that it can predict changes in system capacity and the remaining bus voltage whether it can still be burdened or has experienced overload conditions. In this study, a contingency analysis was conducted on the Ombilin PLTU's own usage system with 5 scenarios to see the results of voltage and performance index (IP) when contingencies occurred with 5 scenarios then ranked. Based on the results of 5 scenarios, the highest voltage obtained in scenario-3 is 6.18 kV with a performance index (IP) of 2.4915 and the lowest voltage in scenario-4 is 6.13 kV with a performance index (IP) of 3.1526.

Abstract

Maintenance of distribution substations is a mandatory activity to minimize damage to electrical equipment. The state electricity company (PLN) of Ciputat's customer service implementing unit (UP3) as the executor is currently carrying out preventive maintenance with the total blackout method, this causes electricity distribution to consumers to be cut off. As a result, PLN suffers losses in terms of achieving the system average interruption duration index (SAIDI). So, we need a zero-downtime maintenance method in order to improve the maintenance of concrete type distribution substations without turning off the electricity supply to consumers and suppressing the SAIDI value of maintenance. Maintenance observation methods, trials, SAIDI values from the results of maintenance are used as references and assumptions for the maintenance plan of distribution substations for the following year. The zero-downtime maintenance method was successfully applied to the CP227 substation without going out on the consumer side, resulting in a maintenance SAIDI value of 0 (zero) minutes per customer and successfully reducing the duration of outages during maintenance by 100%. The total SAIDI value is 56.04 minutes per customer per year from the maximum SAIDI limit for maintaining PLN UP3 Ciputat which is 81.5 minutes per customer per year.
