The demand for electricity will continues to increase each time, this is because of the number of PLN’s customers will continues too to grow each year. Therefore, this is directly proportional to growing the amount of electricity that have to be streamed. With the increasing of the number of PLN’s customers, the provider (PLN) have to increase the amount of electricity supply as well. In the era of globalization, the efficiency of electrical power has always been the main issued, both from the providers and the customers. Therefore, the realibility of distribution system of electrical power will been the main issued as well. The index that showing the reliability of the distribution system of electrical power is SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interuption Frequency Index). As small as the value of the indexes, both SAIDI and SAIFI is so the more reliable the system, which means the efficiency of the distribution system is good (high efficiency). In this research will be discussed about the analysis of SAIDI and SAIFI values of Cahaya feeder, as well as how to suppress the value of SAIDI and SAIFI. Realibilty index SAIDI and SAIFI on Cahaya Feeder in the year of 2017 is 2.277 hours/costumers/year dan 2.406 time/costumers/years. That is reliable based on SPLN 59:1985 standard.

Power plant distribution by considering load change towards time is the development of conventional power distribution because it calculates the ramp rate unitr parameter of power plant. Power distribution of thermal power plant under the load condition that change toward time is used to determine the optimum generation schedule so that it can fulfill the load demand with minimum operational cost when sharing the limitation of system and operation throughout the whole period of generation. Spinning reserve is also considered in power plant distribution, since spinning reserve is used for maintaining the system’s constraint of each operations. In this case, if one unit of power plant is failed, there must be any capacity that could supply the power from another unit to accomplish such condition that happens within a period. This research uses quadratic programming to accomplish power distribution that calculates load change toward time, thus solve power distribution without trespassing the ramp rate parameter and spinning reserve which has been specified. Three unit of power plants were used in this research with short - term load demand and specified ramp rate . From the analysis of results, it can be seen that quadratic programming is not violate constrain ramp rate of power plant, whilst conventional method can not do the calculation of generation with a ramp rate constraint. The result analysis also shows that generation cost using quadratic programming is cheaper ($46659,49) compared to that of conventional method ($47064,01).

One of the operating disruptions that occur in the synchronous generator is the loss of excitation. Where this interference will cause the generated reactive power generator is reduced even lost so that the synchronous generator must absorb the reactive power of the system. If this condition occurs continuously can cause damage to the stator coil, will occur worsening insulation and the stator end iron so as to cause short circuit, or interruption of soil relations in the future. So to anticipate the impact of such disturbances required a protection system. The protection system used in PLTGU Muara Tawar GT unit 1.3 is a minimum reactance relay. This jurnal discusses how to determine the value of loss excitation protection setting using minimum reactance relay and offset relay mho so that synchronous generator can work optimally. From the research calculation the minimum reactance relay usage will work on XA-setting value zone (-2.55 p.u) with 0.5 seconds delay time, XB-setting (offset) of -0.1156 p.u with 0.5 seconds delay time. As for offset relay mho will work on zone 1 and zone 2 for offset value of -0.109 p.u with delay time 0.1 second. As for zone 1 for the base impedance ( ) of -1.0 p.u with a delay time of 0.1 seconds and zone 2 synchronous reactance value ( of 2.423 p.u with a delay time of 0.5 seconds. From those results it is considered sufficient to detect the loss of excitation in the synchronous generator.
