<![CDATA[Changes in the load of a generator are always changing according to the needs of community demand. On the generator side of the Teluk Sirih PLTU using charcoal brush media as a reinforcing field. Where excitation plays an important role providing DC current to the generator rotor to create an intersection of electromotive forces. Changes in generator load that are always changing can have an impact on damage to equipment such as generators, and excitation. Where on December 6, 2017 the excitation current reads low at 473.7 amperes directly proportional to the armature current of 1404.2 amperes, the resulting power will also be low at 13200000 watts and a frequency of 49.9 Hz, creating a magnetic flux of 0.125 Weber that is larger or feels heavy so that the generator rotation is low at 2999 rpm and vice versa. Therefore the role of excitation takes over in order to provide greater current so that the field strength is maintained stable. Increasing the excitation current (If) results in a greater induced electromotive force (Ea). This increase in Ea also impacts the terminal voltage (Vt), causing it to vary. This relationship demonstrates that higher excitation current leads to an increase in terminal voltage, which is essential for maintaining voltage stability. To stabilize the low terminal voltage resulting from load changes, it is necessary to amplify the field gain current. This can be achieved by increasing the excitation current on the synchronous generator rotor. Understanding the characteristics of the excitation system allows for minimizing and avoiding damage to the generator caused by both overexcitation and underexcitation, ensuring the maintenance of a stable terminal voltage.]]>

<![CDATA[In the distribution of electricity from electric power sources to consumers who are located far apart, they always experience losses, namely in the form of voltage drops and power losses. However, the voltage loss that occurs in the process of distributing electrical energy is a waste of energy if it is not controlled optimally. Concerning the quality of service, the main factor which becomes the benchmark is the continuity of service and the quality of service voltage. The impact of these losses results in low levels of service quality to customers. Analysis of voltage drop and power loss is needed to determine the size of the voltage drop at the end of the DPRD feeder network. The calculation of voltage drops and power loss uses simulation results of ETAP method. The results of mathematical calculations and simulations are analyzed to determine the factors that cause the voltage quality at the end of the DPRD feeder network to be below the standard service voltage of 20 kV. The results of the analysis and simulation show that the factors that cause the voltage quality at the end of the DPRD feeder to be below the standard of service quality level are the transformer loading system, the type of conductor, and the distance of the substation to the far end of the feeder network. Then the problem was resolved by changing the type of conductor and reconfiguring it by shifting part of the load to the Lampegan feeder so that the voltage profile at the end of the DPRD Feeder was initially 17.527 kV after reconfiguration increased to 18.137 kV.]]>

<![CDATA[Three-phase induction motors are one of the main components in various industries. To ensure optimal performance and prevent damage to the motor, a reliable speed monitoring and protection system is needed. Considering the difficulty of technicians or engineers in monitoring induction motors in a factory, this is the main thing that is happening at the moment. In this research, researchers designed and implemented a LabVIEW-based 3-phase induction motor speed monitoring and protection system using a Variable Speed Drive (VSD) and controlled by OUSEAL PLC. The monitoring system design or as an HMI (Human Machine Interface) was designed using LabVIEW software via RS-485 serial communication using the Modbus RTU (Remote Terminal Unit) protocol. To set the desired motor rotation speed, namely by changing the frequency value entering the motor, this setting can be adjusted via the LabVIEW interface. Furthermore, the protection system is designed using the error code feature found on the VSD and uses a thermocouple sensor to protect the motor temperature so that if the system experiences a disturbance, the induction motor will stop automatically and then display the error code or disturbance that occurred. The designed system works in accordance with the design, control and monitoring of the rotation speed of a 3 phase induction motor which can be controlled using the LabView application interface. From the results of the research that has been carried out, it is stated that changes in the frequency value entering a 3-phase induction motor will result in a faster rotation speed of the motor produced.]]>

<![CDATA[Telecommunications technology continues to undergo advancements. The enabler of communication in the field of telecommunications is the telecommunications equipment installed on a BTS tower. These devices are constantly being updated to improve the service provided by the provider to meet the needs of customers. One of the network technologies currently used is 4G LTE. To enhance the network service, one of the measures taken is performing a swap or upgrade of the telecommunications equipment on a BTS tower. The upgrade of telecommunications equipment is also influenced by the population in the vicinity of the BTS tower. This allows for the replacement of telecommunications devices with ones that have broader coverage and better signal quality. This research, we discuss the issue of network capacity shortage in the Cibeureum area, South Cimahi. This is indicated by the addition of AAUs to the BTS tower in Pusdikom, Cibeureum. This research found data that South Cimahi is the most densely populated area in the city compared to other districts. Therefore, the addition of AAUs is highly effective for this issue. It is known that the AAUs are added to replace the RRUs on the tower. This is because the capacity and transmission channels of AAUs are greater than RRUs. The addition of AAU with 32T32R specifications to the tower improves signal quality with the following parameter values: RSRP(dbm): -68, -72, -76; RSRQ(db): -11, -10, -10; and SNR(db): 1, 1, 4. These values are categorized as good, indicating that the addition of AAU to the tower can effectively increase network capacity and transmission channels, thereby improving network quality in the area.]]>
