Abstract

Gardu induk merupakan salah satu bagian penting dalam sistem transmisi menjadikan gardu induk ini harus sangat diperhatikan karena jika terjadi kegagalan operasi pada gardu induk maka akan terjadi pemadaman bagi konsumen. Banyak cara yang dilakukan agar keandalan penyaluran tenaga listrik tetap terjaga. Berdasarkan hal tersebut pada sistem distribusi, efisiensi dapat dilakukan salah satunya dengan meminimalisir jatuh tegangan (drop voltage) pada saluran dan mengurangi daya reaktif yang terjadi. Tujuan penelitian ini untuk mengetahui aliran daya yang dibutuhkan trafo daya untuk mensuplai penyulang dengan rugi-rugi daya yang diperbolehkan. Serta mengetahui berapa besar rugi-rugi daya yang terjadi dan perubahan rugi-rugi daya sebelum dan sesudah perbaikan. Metode Newton-Raphson akan digunakan untuk menganalisis aliran daya pada sisi penyulang Gardu Induk Denai. Hasil pengukuran rata rata Arus beban puncak pada sisi penyulang trafo daya I dan trafo daya II adalah 1159 A dan 644 A. Cara yang dilakukan untuk mengurangi rugi-rugi daya pada sisi penyulang Gardu Induk Denai dengan mengerubah luas penampang penghantar yang di bantu perangkat lunak ETAP. Hasil penelitian rugi-rugi daya pada saluran penyulang trafo daya I dan Trafo daya II Gardu Induk Denai adalah sebesar 51,58 kW dan 25.381 kW. Setelah dilakukan perbaikan maka rugi-rugi daya yang dikurangi sebesar 30,89 kW. Perbaikan luas penampang kabel merupakan salah satu acara yang efisien untuk mengurangi rugi-rugi daya pada saluran.

Abstract

The use of capacitors in electrical systems is widely known for their function to improve power factor and voltage profile while minimizing power losses. It results from the reactive power correction provided by capacitors within the system. It is believed that proper placement and size of capacitors can enhance the electricity quality in power systems. Therefore, numerous methods have been developed regarding the allocation and sizing of capacitors. In this research, a meta-heuristic method, Particle Swarm Optimization (PSO) is applied to find the optimal allocation and sizing of capacitors in order to reduce losses. The method has also been improved by modifying the value of inertia weight to optimize the algorithm's performance in finding the solution. The method is tested on an IEEE 34 bus radial distribution system to observe its performance and effectiveness in identifying the solution. The power loss in the distribution system plays the most important role in the economic operation of the power system. It will be used as a fitness function for each particle in the algorithm. The obtained test results include the size of the capacitor and the optimal placement of the capacitor installation.

Abstract

Industry is one of the economic sectors that plays a role in processing environmental resources into products with higher utility values. This process includes design activities, industrial engineering, and service provision. Matra Abadi Workshop, a manufacturing industry that in its operations produces harmonic currents in the electric power system network, especially in low-order harmonics such as 3rd, 5th, 7th, 9th, and 11th. To reduce the negative impact of harmonics on the power system, the use of passive harmonic filters is required. Among the types of filters used, single tuned filters are a common choice because of their simple construction and effectiveness in reducing certain order harmonics that exceed the IEEE 512–2014 standard limits. This study discusses the implementation of both types of filters in a manufacturing industry environment. The harmonic reduction process is carried out through filter design and testing using Matlab/Simulink software-based simulations. The simulation results show that after the application of passive filters, the harmonic current levels in all load configurations were successfully suppressed to within the IEEE 512–2014 standard limits. The reduction in Total Harmonic Distortion (THDi) after the application of the single tuned filter was recorded in the range of 17.86% to 11.06%. In addition, there was an increase in the power factor from 0.68 before the filter was installed to 0.91 after the installation, which indicates an improvement in the overall power system performance.
