Abstract

Solar energy is an unlimited source of energyand its availability will never run out. It can be converted into asupply of electrical energy. And saved into battery throughconverter. There are many people who convert solar energy intoelectrical energy. Unfortunately, when stored in the battery, it isstill necessary to adjust the output voltage of the converter. So, itis need a controller to do it. To solve the problem, we proposeFuzzy Logic Controller (FLC) and Adaptive Neuro FuzzyInference System (ANFIS) control to adjust output voltage whilethe input voltage is fluctuative. We will compare which twocontrollers are better. We used the constant voltage method, andafter we ran the simulation, we got ANFIZ better than FLC.Because we get setting point faster when using ANFIZ. Theresult, it need time 0,04s to get setting point on output voltage

Abstract

Transformer is a very important thing for distributing electricity. One of the troubles that happen to transformer is overload which can shorten their life or worse case it can cause an explosion. Up until now, PLN Corporation still doesn’t have mitigation alerts for overload. Load monitoring is still done manually along with inputting data on the web. It can cause false inputting of data due to human error. So, this research was made that can be monitored on the web and shown as a diagram with real-time parameters. This research can also be moved to its place because it’s portable. This research uses a current sensor and voltage sensor also GPS which is processed by a microcontroller and then the result is shown in LCD and monitoring web by ESP8266. Hopefully, this research can help PLN mitigate overload and reduce human error, remembering that substation transformer costs a lot. The result of the test shows that this system could read voltage and current values with average sensitivity 0,1803% and 1,15%. Besides, it has GPS to detect location when it moves place and it has high accurate.
