Abstract

Utilizing solar energy as an alternative energy source for Indonesia's electricity needs is very appropriate because it is located in a tropical area with hot sunlight available all year round. Considering that in rural areas in Indonesia there are still many public road accesses that are not equipped with street lighting and the problem stems from the use of conventional electrical energy as a source of street lighting. The use of photovoltaics (PV) as a tool to produce electrical energy with the advantages of being environmentally friendly, low maintenance costs and zero emissions and the energy needed is available in nature and is always renewable (renewable energy). The 1 DOF (Degree OF Freedom) solar tracker mechanic is used to find the point where the sunlight is optimal, which aims to produce maximum solar panel output during energy conversion. Based on the test results, it can be concluded that solar-powered public street lighting (PJU-TS) using a mechanical solar tracker delay of 2 seconds produces a daily energy conversion of 235.20 Wh, which is more optimal than solar-powered public street lighting (PJU-TS) with solar tracker delay. 2.5 seconds amounting to 218.75 Wh and solar powered public street lighting (PJU-TS) without a solar tracker amounting to 171.34 Wh.

Abstract

One of the advantages of solar cells is their ability to generate electricity without creating noise or air pollution. However, they have the disadvantage of increasing temperature due to continuous exposure to solar radiation, thereby decreasing solar cell efficiency. A solution to mitigate this effect is a cooling system for solar cells. Cooling methods for solar cells consist of active and passive methods. Active cooling methods for solar cells require power consumption, necessitating analysis and evaluation of their efficiency in practical applications. This research analyzed the power efficiency of a cooling system using a water pump, peltier, and fan. The power measurements generated by the cooled solar cell produced a power efficiency of 8.64%, compared to a solar cell without cooling. Meanwhile, the average power efficiency over six data collections was 7.82%.

Abstract

In the electric power system it does not always run normally. There are many disturbances or disturbance anomalies that can disrupt the operation of the system. One of them is at the Sekarputih main substation. last two years, the channel has experienced five short- circuit disruptions. As a result, electromagnetic distance relays must be replaced with digital distance relays equipped with reclosers. The reclosers will function when there is a relay disturbance on a trip and automatically reconnect. The disruptions may occur due to damage brought by unstable weather conditions. Indirectly, the value of relay settings will change and deviate from the PLN (state electricity company) standards. Therefore, relay re-setting was performed using two methods: the Fuzzy Mamdhani and the ANFIS methods. Using the Fuzzy Mamdhani method, the relay distance settings were as follows: Zone 1 = 0.523 Ω, Zone 2 = 0.54 Ω, and Zone 3 = 1.58 Ω. Meanwhile, the relay distance settings by the ANFIS method were: Zone 1 = 0.432 Ω, Zone 2 = 0.65 Ω, and Zone 3 = 1.22 Ω. The previous values of relay distance settings by PLN were Zone 1 = 0.587 Ω, Zone 2 = 1.046 Ω, and Zone 3 = 1.766 Ω.
