Abstract

Control and operation of a microgrid can be operated at grid connected or islanded modes. In this paper, the microgrid consists of a Diesel, PV modules with a distributed energy storage system, loads, and inverter. The purpose of power management is to control the stability of the system to cope with changes in load and interconnection with other networks. The stability of the microgrid is also obtained by setting the load connected to the system. Power management is also controls the operation of each plant based on the condition of the energy sources used as a source of generation. In islanded mode, the main goal of power management is to stabilize the system, in terms of frequency and voltage. In grid connected mode, typical objectives are to minimize the price of energy import at the point of common coupling (PCC).

Abstract

In PV systems connected to the grid requires a kWh meter to measure the amount of power delivered to the grid, and an inverter to convert the DC voltage generated by PV into AC voltage. The latest generation of Inverter using the high switching frequency to obtain the inverter with good efficiency, small in sizes and lightweight. This led to the emergence of harmonics to the grid through the instrument of kWh meter, and caused the kWh-meter is not working properly. This study is intended to obtain the minimum value of the switching frequency which affect the results of measurement of Digital kWh meters. Kwh-meter tested by varying the switching frequency which is obtained from various types of inverters and from the simulator of switching of high frequencies.

Abstract

Priority loads, in micro grid is preferred load to always get the power supply. Battery function, in micro grid, in addition, functioning as a storage energy, it also serves as a stabilizer of network, due to intermittent of energy sources, both solar and from wind. As energy storage, battery is intended to supply energy when other sources of energy is not available. So far, the mechanism of battery operation, distributed on each generation, so that when operation standalone, battery capacity is not in optimal level. In this study, proposed, method of centralized control battery operation, which would regulate the use of battery operation, especially to supply the load priority. So that the power supply from the battery to the load priority, it would be optimal in optimal level when other sources are no longer, by utilizing parameters weather and load forecast.

Abstract

Power transformation of pqr-coordinate modified by Euler angle rotation method used in analysis of the IGBT active filter circuits as the instantaneous power theory is reviewed. Twice and three times rotation of Euler angle already conducted and produced a matrix transformation different from the Kim-Akagi’s model. Method of Fourier integral in the Voltage Source PWM Converter be done so a harmonics characteristic can be known and may be reduced. Value of Euler angles in frequency domain determined as a carrier harmonic waveforms. This approach is gives slightly different than that has understood so far.

Abstract

The pandemic has changed the usage pattern of electrical appliances in buildings. This new pattern can create new problems in terms of power quality and thus affect the electrical system’s reliability. The purpose of this study is to determine the power quality of the Dean Office Building, Faculty of Engineering, Universitas Indonesia, and propose alternative solutions to its problems. To determine the quality of electric power, the related parameters such as voltage, current, power factor, and harmonics are measured first. The measurement results are compared with existing standards. If these standards cannot be met, damage to electrical equipment can occur. Out of eight parameters, three did not meet the criteria. First, overvoltage on average voltage with the range of 231.5-232.8 V. Second, IHDi nominal on the 3rd, 5th, 7th, and 15th harmonics for Thursday, April 7, 2022 on 06:11 with the value of 70.3%, 55.34%, 27.1%, and 8.07%. And third, the minimum power factor for the T phase with the value of 0.7219 is still less than 0.85. Possible solutions include checking and changing the supply transformer tap-changer, making an energy monitoring system and wiring diagram for understanding the load profile of the building, and using a single-tuned filter for harmonic currents.

Abstract

The increasing use and use of electricity in Indonesia causes the potential for greater losses in the transmission and distribution system. This causes many problems that arise, one of which is the corona in the transmission and distribution system. Corona mapping can only be detected through several ways, namely sound, light and distinctive smell. In this thesis, the aim is to detect the corona with the characteristics of a distinctive sense of smell, then the results of the detection are compared with the calculated corona losses. This distinctive odor is the smell of ozone which is produced from ionization at high voltage with the surrounding air, namely oxygen to form ozone molecules that are not permanent. The metal electrode to be tested is the copper tip metal. After testing the voltage of the appearance of the corona occurs at 7kV, high voltage when testing the tip of the copper metal point at a voltage of 21 kV is greater than the corona losses. The greater the voltage, the greater the corona losses generated.

Abstract

The availability and reliability of electrical energy has become the backbone of society, so periodic maintenance needs to be carried out to avoid short breakdowns and technical malfunctions as well as to improve electrical and environmental safety. Overhead transmission line is an important part of the transmission network and their health status is an important foundation for ensuring the reliable supply of electricity to the power grid. The health index (HI) is a value that reflects the health status of high-voltage transmission lines obtained by combining the normalization of component ratings on certain parameters and calculation methods. This study shows that the condition of assets, electricity and the environment have an effect on determining the soundness index of the Anyer-Asahimas 150 kV overhead transmission line and can be a guide for its maintenance. The final health index value shows 92.8% meaning that the transmission is not only safe in terms of equipment but also safe in terms of electrical and environmental safety aspects.

Abstract

Good power quality is required in health facilities since the increasing use of microprocessor-based equipment. Poor power quality in the electric power system can cause medical equipment in health care centers to malfunction and give incorrect medical diagnoses. Since 2020 we are facing a new type of Virus (Covid-19), this virus requires special laboratory construction with specific air conditioning systems (temperature, humidity, and pressure) to process specimens. This paper presents measurement results of harmonic distortion characteristic by Variable Frequency Drive (VFD) of Heating Ventilation Air Conditioning (HVAC) system in PCR Laboratory at Clinic A. The VFD in this system is used to adjust the rotation of the exhaust fan and outdoor unit. The measured voltage, current and power are used to assess power quality. The main power quality problems found in medical facilities are voltage flicker, neutral currents, and total harmonic distortion (THD) values. The measurement of total harmonic distortion (THD) is used to find the source of the harmonics. Potential problems can be identified within the facility. The results of this study can be used to develop, test, and validate the system that has been used.
