Abstract

At the company PT. PLN (Persero) ULTG Madiun carried out many tests relay, one of which is intertrip testing relay distance. Intertrip testing relay distance is a test carried out between 2 (two) relay distance conducting bays in main substations that face each other. Intertrip testing relay distance must be done if replacement occursrelay, replacement of teleprotection equipment, changes to protection schemes, and changes to logic circuitsrelay which is related to the send or receive signal from the opposite substation. However, this test requires synchronization between two intertrip test tools relay distance at each substation. In this final project, it will be designed Time Syncronization As A Tool For Intertrip Relay Distance Testing, to make things easier for PT employees. PLN (Persero) ULTG Madiun when synchronizing two intertrip test equipment relay distance. All process control of this tool uses ESP32 Devkit V1. Meanwhile for displaying setting time for testing can be seen on the web assisted by GPS NEO-6M. The results obtained when testing the Dolopo by Ponorogo R and S phase distance intertrip relay were carried out at 12.00.00, experiencing a delay time of 0.0553 seconds when the PMT tripped. Meanwhile, the Dolopo by Ponorogo T phase distance intertrip relay test was carried out on 12.09.00 and experienced a delay of 0.0529 seconds when the PMT tripped. From two intertrip relay distance tests, the trip time delay is no more than 0.1 second.

Abstract

Water pollution due to human activities causes high levels of household wastewater called greywater. To reduce the impact of water pollution from greywater, wastewater needs to be processed to be safer for the environment. By utilizing technology and independent energy sources from Photovoltaics, a system was created that can purify wastewater and can be controlled and monitored using the Internet of Things. The research entitled "Monitoring and Control System for Photovoltaic Powered Greywater Purifiers Based on the Internet of Things (IoT)" aims to monitor and control water to obtain processed wastewater that produces cleaner water quality. This system can monitor battery charging for pump sources on filters in real time using IoT integrated with an Android application. The way this tool works is by utilizing the ESP8266 nodeMCU as a communication intermediary, Arduino as the tool control center, relays for control, voltage sensors to detect battery and pump voltage, ACS712 sensors to detect charging and pump currents, turbidity and pH sensors to detect water conditions. The results of this research are that the system can monitor water conditions, voltage, and pump current when filtering while controlling the pump based on water conditions, as well as monitoring the charging voltage and current from the PV to the battery.
