Abstract

The electric power distribution system on the transmission line side is carried out at the substati on, which contains several bays. However, containing the primary equipment discussed in this study regarding the Current Transformer (CT) of the CT OSKF-170 type, so that the electric power distribution system can be carried out optimally. The research location is substation area (GI), where the maintenance side is optimised and tested to prevent extensive damage to the substation's electric power distribution. If the CT has damage or disturbances such as current leakage that create inefficient power distribution losses, it can be replaced. Thus, this study examined the results of the insulation resistance measurement of more than 1000 G and on the secondary side the results were 100-500 MΩ. Then, the value of grounding resistance in the R, S, and T phases was less than 1Ω, the tan delta test yielded a measurement value of less than 1 percent, and the turns ratio in the transformer corresponds to the ratio value on the CT OSKF-170 nameplate. The outcomes of the tests were satisfactory in accordance with the criteria for CT maintenance standards.

Abstract

Wind energy conversion system, one of the main components is a Permanent Magnet Synchronous Generator (PMSG). During the past two decades, many types of per- manent magnet generators for wind power applications have been the research topic. This study focuses primarily on designing a PMSG to create, simulate, and analyze an internal permanent magnet topology with twelve plots and eight poles. We limit with the simulation was carried out at a rotational speed of 1000rpm, and a type of permanent magnet material, Ceramic 11, SmCo 26/26, and NdFeB 48/11. The result of the analysis is that permanent magnets applied in the design of a generator impact its output power and efficiency. At 15 Ω and 60 Ω loads, SmCo 26/26 and NdFeB 48/11 are the only ones that fulfill the specified requirements in this investigation. The permanent magnet type with the most optimal characteristics is Neodymium Iron Boron 48/11 because it has a high flux density, thus causing the electrical energy generated to be greater than other types of permanent magnets. The 48/11 NdFeB permanent magnet generates the most output power, 2110.86 W when loaded with 15 Ω. The best efficiency of 89.38 percent for the PMSG 12 slot eight poles occurs when the load is 15 on the 48/11 NdFeB permanent magnet.

Abstract

PLTS 1 MWp on-grid at the Sumatra Institute of Technology (ITERA) campus comprises solar modules, inverters, DC cables, and protection equipments assembled in a compact system. Each of these components has a role in transmitting the electrical energy generated by the solar module to the electrical load at ITERA. This paper will discuss the power losses generated by PLTS components, especially the DC distribution cables used. The simulation of PVSystV6.81 obtained 1.98% of the losses resulting from the distribution process on the DC cable. The simulation results were compared with the measurement results from the solar fusion software, which records the power components generated by PLTS ITERA such as voltage, current, power, etc. for each string connected to the inverter with a data collection duration of 5 minutes (12 hours per day 06.00 – 18.00). Based on data obtained from fusion solar in August and formula calculation, the lowest average percentage loss of energy from DC cables is 0.6542% on inverter 6, and the highest is 0.6718% on inverter 1. The difference losses of each inverter are caused by disturbances in the DC cable distribution line from the module to each inverter, such as short circuit current to ground.
