Abstract

High resistance grounding one of the ways ptotection generator for the single phase earth fault. High resistance grounding utilizes a distribution transformer with a primary voltage rating greater than or equal to the line to neutral voltage rating of the generator. The distribution transformer should have sufficient overvoltage capability so that it does not saturate on single line to ground faults with the generator operated at 105% of rated voltage. The power dissipated in resistor is approximately equal to the reactive volt-amperes of the zero sequence capasitive reactance of the stator windings. For High resistance grounding to be effective, the size of resistor must be carefully selected for each system. IEEE Standard C37.101 provides a detailed example of how to determine the size of the ground resistor to meet the requirements cited above, as well as calculate the resulting ground currents and voltages.

Abstract

Electrical energy is generated in power station and transmited to the consumers trough transmission lines and distribution lines. Transmission lines connected a power station and a substation and can connected substation and a substation. Transmission lines can be overhead line or underground cable. Sometimes the line consists of overhead lines combined with underground cable lines. Connection between overhead lines and underground cable in done in transition station. If a line to ground fault happen there will be a gradient voltage in the area of transition station and in thesubstation. In this papper will be studied the gradient voltage in the transition station related the length of underground cable line.

Abstract

Increasing the amount of induction motor power available then the current on the induction motor will grow larger but to reduce the current is too large can be overcomeby increasing the voltage or increased voltage. In addition, one of the disadvantages of the induction motor is not able to maintain its speed with a constant when there is achange of load. If there is a change in load then the speed of the induction motor will decrease. Based on the results of the repeater design performed shows that a largeinduction motor that is Start UP BFP (Boiler Feed Pump) with 5191 KW at flood pumps Pluit Reservoir North Jakarta can be started directly if the flicker problem can be solvedimmediately and using spindle feeder network by considering relay aspect Used, both the inverse relay and the instant trip relay. The design results using almunium cablemeasuring 95 mm2 for 20KV voltage and 400mm2 almunium cable for 10KV voltage, 20 / 10KV transformer.

Abstract

Medium voltage feeder is a media for distribute power electric from main stasion to the customer. But in the fact, the feeders almost have a disturbance, such as short circuit disturbance. So is needed protection system which is fulfill the qualification such as sensitivity, realibilty, and speed, which all of that depend on the accuration of tool protection setting. In general it used for medium voltage feeder are Over Current Relay (OCR) and Ground Fault Relay (GFR), that is relay which has function to instruction the PMT for open the circuit, so SUTM/SKTM which has disturbance separate from nerwork. In this final project it will discuss about condition in the protection system for medium voltage 20 KV network in PLTD Merawang Bangka.

Abstract

Transmit power, Substation electrical components have a Parent in the form of a power transformer for transforming electrical power, by changing the magnitude ofvoltage while frequency remains. One of its kind based on the voltage i.e. transformer 500/150 kV and 150/70 kV Interbus commonly referred to as Transformer (IBT).Transformer is the heart of the distribution and transmission of which is expected to operate at maximum. In order to function properly, then the transformer must be kept andcared for properly using the proper equipment and systems. As the State-owned electricity company, PT PLN (Persero) trying to supply electrical energy optimally. To maintain thequality of the electrical energy is transmitted, system security and maintenance of the electrical equipment of a much needed parent booths. If the transformer is experiencinginterference, then the distribution of electric power can be interrupted, so a transformer requires protection equipment. On the transformer often experience internal disturbancesso that the main safeguards are required i.e. differential relay useful to secure the entanglement of the transformer in case of a disruption. Rele is very selective and worksso quickly that the system can isolate the internal disorder as quickly as possible without resulting in further damage.

Abstract

Connection between substations and distribution substations using ground cables often occurs due to mechanical, thermal, and over voltage faults or due to defective or damaged materials. The disturbance flow will flow on metal parts of the equipment and also flow in the ground around the substation. The purpose and benefits of this study was to analyze the differences in the impedance value of the cable sheath at the distribution substation to the value of the voltage change (transfer voltage) dipengaruh by land lines, using data cable PT Sucaco Tbk, cable type of three core types NA2XSEBY with cross-section 70 mm2, 150 mm2, 240 mm2 and two substations are a substation a and substations b with different distances of 400m, 500m, 600m, 700m, and 800m, assumed soil resistivity is 100Ωm, with 1m cable burial depth. The greater the distance between the substation then the ratio of voltage increase at the source with the transfer voltage will be smaller, which for the cross-sectional area of the cable 70 mm2 with a distance of 400 m then kt 0.9098, while for a distance of 500 m of 0.88862, for 600 m of 0.8717 , For 700 m of 0.8112, and for 800 m to 0.7422. The bigger cross section of the ground cable, the greater the kt ratio, it is seen in the substation with a distance of 500m where the area of cross-sectional 70 mm2 then the big kt is 0.8862, while for 150 mm2 of 0.9207, and for 240 mm2to 0.9212.
