Abstract

The electromagnetic distance relay at the Sukolilo substation has been replaced with a digital relay equipped with a recloser. If there is a disturbance, the relay will trip and reconnect automatically. The setting values have changed as a result of this replacement. The purpose of this study was to determine the value of the distance relay setting at the Sukolilo substation using traditional calculations, which would then be implemented in a computer program developed by PLN Ltd. It also found out the results of calculations per zone included in the distance relay zone. This study employed a fuzzy method with digsilent software. The research data comprised data on SUTT installed at the Sukolilo substation, data on conductor relay settings at the Sukolilo substation, data on short circuit currents, and transformer ratios. The simulation results in this study indicated that the distance relay had a setting value that was not in accordance with the standard in the old setting of the Sukolilo substation zone 1 for protection (175.42%), while the calculation results showed that zone 1 protected 58.44%. The new impedance setting covered zone 1 = 0.338, zone 2 = 0.862, and zone 3 = 1.488, whereas the old impedance setting showed zone 1 = 0.1126, zone 2 = 0.2924, and zone 3 = 0.4128. The old setting time and the new setting showed a big difference in that the old setting time was 0.25 seconds with a range of 175.42% while the new setting time was 0.25 seconds with a range of 58.44%.

Abstract

The need for the staple food chili is quite high, while agricultural land in big cities is being converted into residential areas. Meanwhile, chili plants can grow and develop in a limited environment by controlling humidity, temperature and light intensity. This research aims to analyze a greenhouse monitoring control system for chili plants based on DHT 22 temperature sensor input and YL-69 humidity sensor. The method used is fuzzy mamdani to control humidity according to what the plants need. The system test results can maintain the soil moisture of chili plants at 60% - 80%. The DHT 22 sensor test worked quite well with a error temperature sensor of 0.00% - 1.12%. Overall, the temperature and humidity control system in the greenhouse can maintain stable humidity for chili plants at the desired set point.

Abstract

The transmission system plays an important role in maintaining the continuity of the distribution of electrical energy from one region to another. Disturbances in transmission lines are caused by short circuits, overloads, lightning surges, natural disturbances and others. For this reason, a protection system is needed that is reliable and can identify disturbances quickly while protecting the disturbed part of the system from other parts that can still operate normally. However, the protection system can experience operational failure due to various factors, therefore, apart from the main protection, backup protection is needed which can work when the main protection fails to work. Distance relays can be used as primary protection as well as remote backup protection on high voltage overhead lines. Meanwhile, the overcurrent relay is used as local backup protection if the distance relay fails to work. In this paper, a protection system is designed for the Buduran Main Substation channel using a combination of distance relays as main protection and overcurrent relays as backup protection using simulation method the Digsilent Power Factory. The overcurrent relay will trip at 0.5 and 0.15 seconds. From the Load Flow results, the value is obtained = 3,615 kA, = 4,67 kA and The range impedance according to the conductor cable data at the Buduran region 0,9676, Zone1 1 0,79Ω; 80%, Zone2 1,19Ω; 120% dan Zone3 as 1,48Ω is 150%. Thus the research can be declared successful in carrying out overcurrent protection
