Abstract

This study aims to analyze the performance of the backup power system (emergency generator) at the West Sumatra Maritime Polytechnic. The reliability of the electricity supply is very important to support the continuity of educational activities and institutional operations. A backup power system is needed to anticipate power outages that can hamper these activities. This study was conducted using the method of literature study, field observation, interviews, documentation, and analysis of technical data obtained. That generator 1 received a load of 172.76 kVA (138.21 kW) and generator 2 of 294.62 kVA (235.70 kW), with a larger load distribution on Generator 2. The demand factor was 35.37% (generator 1) and 58.92% (generator 2), respectively, while the load factor was 0.35368 and 0.58924. These values indicate that the actual load has not reached the maximum capacity of the generator, so there is still a power reserve available. The utilization rate of generator 1 is 28.29% and generator 2 is 47.14%, which means both are still operating within safe limits, even though generator 2 is utilized more. During 5 hours of operation, fuel consumption is 225 liters and 255 liters, respectively, proportional to the size of the load carried. Voltage drops are still within the tolerance limit (?5%), namely 2.53 Volts on generator 1 and 2.40 Volts on generator 2. Power losses in the 360 mm² NYFGbY cable are also relatively small, namely 4.164 kW and 3.76 kW, which indicates the efficiency of the electrical system installation. Thus, the existing backup power system is still reliable and efficient, although further evaluation is needed for load distribution and performance optimization.

Abstract

The quality of electrical installations is highly dependent on the implementation and application of electrical installation standards, namely PUIL 2011 (General Requirements for Electrical Installations) and other supporting regulations. The implementation is to ensure the safety of humans, tools, and buildings, as well as the main requirement for electrical installations to be carried out safely, reliably, and environmentally friendly. So it is necessary to conduct an evaluation of the electrical system to ensure the safety, reliability, and efficiency of the system are in accordance with electrical installation standards. In the cadet dormitory building, there are several rooms that function as bedrooms, living rooms, pantries, warehouses, and toilets with an electrical system consisting of power outlets, lighting installations, and air conditioning. Based on the results of the study, the total installed load of LVMDP is 104,134 Watts using a 3-phase 250A MCCB with a cable size of 4x240 mm2 NYFGbY. The 1st floor AC panel has a total load of 27,360 Watts using a 3-phase 80A MCCB using a cable of 4x35 mm2 NYY. Lighting Panel & Socket on the 1st floor total load of 9,762 Watts using 3 phase 40A MCB using 4x16 mm2 NYY cable. AC Panel on the 2nd floor total load of 27,360 Watts using 3 phase 80A MCCB using 4x35 mm2 NYY cable. Lighting Panel & Socket on the 2nd floor total load of 5,473 Watts using 3 phase 20A MCB using 4x4 mm2 NYY cable. AC Panel on the 3rd floor total load of 27,360 Watts using 3 phase 80A MCCB using 4x35 mm2 NYY cable. Lighting Panel & Socket on the 3rd floor total load of 6,819 Watts using 3 phase 32A MCB using 4x6 mm2 NYY cable
