<![CDATA[The results of the voltage drop calculation from the MDP panel to the SDP under maximum load conditions (100% loading) show that the largest voltage drop occurs on the Hyundai Lift Power Panel by 0.51%, due to the distance of the conductor to the PP Lift Hyundai being the farthest and the cross-sectional area and the magnitude of the load current being larger than other panels. From the analysis of the comparison of manual voltage drop calculation results against Ecodial simulation, there is an error of 9.8%, while against ETAP simulation there is an error of 5.88%. Based on the results of voltage drop calculations and analysis with manual calculations and Ecodial and Etap simulations in civil buildings, the percentage of voltage drop results is in accordance with PUIL 2011 Chapter 2.2.3 and IEC 60364-5-52 Table G.52.1 standards so there is no need to make voltage drop repairs because electrical conditions on each floor of civil buildings are still in normal condition.]]>

<![CDATA[The pasteurization module that has been designed and made uses a PLC type TWDLMDA20DTK as its controller with the help of expansion in the form of TM2AMM6HT. The components contained in the module include a solenoid valve, heater, RTD, SRPH1, and a cooling system. The voltage from the source is then connected to the control box and then controlled by the TWDLMDA20DTK PLC and its expansion, namely TM2AMM6HT. All components will work according to the desired system operation, namely the temperature can be stable at 63˚ C for 30 minutes with PID auto-tuning control. This process is carried out by programming a ladder diagram on the TwidoSuite application. The stabilization of the module’s operation is regulated by the auto-tuning method, where this process will automatically produce Kp, Ti, and Td values contained in the Ladder diagram. This process is carried out in order to obtain a stable system operation with the expected parameters. The expected parameters include a low steady-state error value of 5-10%.]]>

<![CDATA[The transmission system is a system that often experiences lightning strikes and can cause back flashover (BFO) if there is a direct strike on the ground wire or on the tower. Lightning strikes can also cause touch voltage and step voltage hazards when lightning strikes the ground surface. Grounding is a safety device that functions to protect equipment, systems, humans and other living beings from electrical surges, especially lightning strikes. The grounding resistance value on the tower must be made as small as possible so as not to cause high tower voltage which can ultimately disrupt the transmission system. The grounding resistance limit according to PUIL 2000 is no more than or equal to 5 Ohms. This study aims to evaluate how feasible the tower and its protective devices are on the tower, including grounding and arresters in the event of a lightning strike. By collecting data, calculating tower voltage and simulating lightning overvoltage with the ATPdraw application. From testing the tower voltage by taking a sample on a tower with the highest grounding resistance of 5.8 Ohms on tower T63, the tower voltage value was obtained at 169.94 when given a current of 20 kA, 345.6 kV when given a current of 40 kA, and 682.03 kV when given a current of 80 kA. By calculation and simulation that the tower voltage value does not cause Back flashover (BFO) so it can be categorized as safe and feasible from lightning strike interference.]]>

<![CDATA[A large load imbalance is caused by the use of single-phase loads in a three-phase system, and poor harmonics are caused by non-sinusoidal loads, which result in losses in the network and poor quality of power distribution. This study aims to monitor and analyze load balance and harmonics in the Graha Polinema Building at Politeknik Negeri Malang. The research is a survey and case study using primary data obtained through direct measurement using a Web-Based Power Quality Meter (PM 5110) to gather data from each SDP panel, and secondary data through observation. From this study, the highest current imbalance value of 133.50% was found in the North 4th Floor SDP Panel of the Grapol Building, exceeding the IEEE 1159-2009 standard, which sets the limit for load imbalance at 30%. Current Harmonic Distortion (IHD) occurred in 8 SDP panels, except for the North and South Water Pump Panels. Total Demand Distortion (TDD) for all panels was within the standard limits. Total Harmonic Distortion (THDv) for all panels was also within the standard limits, with the highest value of 2.37% found in the North 4th Floor Panel.]]>

<![CDATA[In this study, the excitation system used is a static excitation system that uses a transformer and several thyristors connected in a bridge configuration. The excitation system is then implemented on a generator with a capacity of 200 MVA / 15 kV using the MATLAB Simulink R2017b simulation. By using the above circuit, the thyristor ignition angle setting can be adjusted so that it can adjust the excitation voltage and obtain the appropriate excitation current to maintain the stability of the generator output voltage. The simulation was carried out with variations in generator load and using 2 different types of excitation settings. The first setting is to set the thyristor ignition angle to 30° with t=10 ms, at this setting the generator can maintain a stable V out value with a voltage regulation limit of ±5% and the reactive power that can be generated by the generator is +50MVAr and - 40 MVAr. When given a constant excitation at an angle of 35° with t=1 ms, the value of Vout exceeds the expected regulatory limit and the resulting reactive power limit is between +60 MVAr and -100 MVAR where the reactive power does not match the load requirements. This can have an impact on the interconnection system, namely when the reactive power of the generator is greater than the load requirement, the generator with a smaller reactive power will absorb reactive power in the interconnection system and can disrupt the stability of the interconnection network.]]>

<![CDATA[From the research that has been done at the Blitar Square Shopping Center, it was found that the power factor value is still below the standard with an average value of 0.711. Therefore, it is necessary to improve the power factor by installing a capacitor bank. The calculation results show that global compensation requires 12 capacitor banks with a rating of 10.4 kVAR, while sectoral compensation on the chiller load panel requires 7 capacitor banks with a rating of 10.4 kVAR and the foodmart load panel requires a capacitor bank with a rating of 10. 4 kVAR is 6 pieces. In addition, the installation of a capacitor bank also results in an increase in the voltage value in the system, this voltage increase is still below the permissible standard of ± 5%. The simulation of installing a capacitor bank on global compensation can improve the power factor value from 72.99% to 96.97%, with a voltage increase of 0.479% from the initial value of 397 V to 398.9 V, and a decrease in the current value of 24.645% from the initial value. 330.7 A to 249.2 A. While the simulation of installing a capacitor bank in sectoral compensation can improve the power factor value from 72.99% to 93.57%, with a voltage increase of 0.401% from the initial value of 397 V to 398.6 V , and a decrease in the value of current by 21.593% from the initial value of 330.7 A to 258.1 A.]]>

<![CDATA[The length of conductor paths in distribution networks often leads to voltage drop issues and significant network losses. Placing capacitor banks in the distribution network is the primary solution to address these problems. However, optimizing the installation to achieve a significant impact on the voltage level in the network requires complex calculations, especially for very long lines such as in the 20 kV medium voltage network. This paper will use a 20 kV primary distribution system with 10 buses and 9 lines. Based on operational conditions, there are several issues that need to be addressed, and their solutions will be sought through heuristic methods.]]>

<![CDATA[A Variable Speed Drive (VSD) is a device that regulates the speed and rotational force or torque of mechanical equipment. VSD improves efficiency by allowing the motor to operate at the ideal speed for each load condition. In many applications, VSD reduces the electricity consumption of the motor by 30-60%. The energy-saving potential of electric motors is significant as motor systems account for more than 60% of the power consumed by industries. It is due to these advantages that VSD can be used to control the speed of compressor motors, thereby enhancing the performance of the compressor. A compressor motor is a device that compresses air and increases its pressure. To compress air, the compressor requires a driving force, and one of them is the motor. When the output air pressure of the compressor exceeds a certain value, the relief valve will open automatically, allowing the air to remain in the tank even when the motor is still running. During compressor operation, the motor is always started with a high starting current, resulting in high power demand. Therefore, control of the compressor motor is necessary.]]>
