Abstract

The use of electrical energy plays a vital role in supporting the continuity of production processes in industrial environments. One critical area that heavily relies on electrical power supply is in the planning of installing a capacitor bank with a detuned reactor. The primary objective of this planning is to enhance the power factor (cos φ) from 60% to 85.2% during full-load operations and up to 94% when operating as per demand simulations. The evaluation of power quality from the implementation of the Capacitor with Detuned Reactor is conducted through simulations using ETAP 12.6.0 software.The simulation results from ETAP 12.6.0 produce comparative graphs between buses equipped with the Capacitor with Detuned Reactor and buses without it, both during full-load operational conditions and when only operating in simulations. The information derived from the simulation provides a deeper insight into the impact of installing the capacitor with detuned reactor on power factor and power quality within this industrial environment. With this understanding, further steps can be taken to optimize the electrical power system within the industrial setting.

Abstract

Paper ini memperkenalkan sebuah sistem manajemen Trafo Distribusi jaringan tegangan rendah (JTR) milik PT. PLN (Persero) yang disebut dengan Distributed Transformer Management System (DTMS). Trafo Distribusi merupakan asset strategis PT. PLN (Persero) karena keberlangsungan umur trafo distribusi adalah sangat penting dalam menjaga layanan penyediaan energi kelistrikan kepada pelanggan, dan sebagai sumber pendapatan utama.  Jumlah aset yang besar dan luasnya jangkauan pemasangan trafo distribusi menuntut PT. PLN (Persero) berinvestasi lebih untuk memantau kondisi Trafo agar tidak terjadi kerusakan dan mengurangi biaya perawatan. Oleh karena itu peran teknologi informasi saat ini menjadi salah satu investasi yang paling feasible bagi PT. PLN (Persero) dalam menjaga performa aset strategis tersebut. DTMS yang dibangun terdiri atas: (1) perangkat embedded system yang berfungsi untuk melakukan pengukuran dan pengiriman data, (2) perangkat lunak Web Service yang berfungsi untuk menerima data dari embedded system dan (3) perangkat lunak berbasis web untuk penyajian data dan pengelolaan data untuk menjadi sebuah Decision Support System (DSS). DTMS ini dibangun untuk memberikan fungsi peringatan dini terhadap anomali parameter trafo seperti overload, overvoltage dan black out events. Disamping itu, suhu operasi trafo juga menjadi parameter yang menggambarkan kondisi trafo dalam status aman, peringatan atau berbahaya. Embedded system yang dibangun akan mengukur kondisi trafo, kemudian dengan menggunakan protokol komunikasi RF 2,4 GHz dan GPRS, embedded system akan menampung dan mengirim data ke server melalui protokol HTTPS dengan antarmuka pemrograman yang disusun menggunakan format JSON. Setelah mendapatkan data, DTMS akan melakukan perhitungan untuk mendapatkan rekomendasi optimalisasi trafo berupa penyeimbangan, perawatan atau peningkatan daya. AbstractThis paper introduces a Low Voltage Distribution Transformer (JTR) Management owned by PT. PLN (Persero) which is also called the Distributed Transformer Management System (DTMS). Distribution transformer is a strategic asset of PT. PLN (Persero) because it’s lifecycle is highly important for PT. PLN (Persero) primarily in delivering electrical energy to customers, and of course as a main source of PT. PLN’s revenue. The large amount of assets and the broad range of installation of distribution transformers requires PT. PLN (Persero) invests more to monitor and maintain the condition of the Trafo in order to avoid unplanned damage and reduce the cost of unplanned maintenance. Therefore the role of information technology is currently one of the most feasible investment for PT. PLN (Persero) in maintaining the performance of this strategic assets. The DTMS consists of: (1) embedded system devices for data measurement and transmission, (2) Web Services software for receiving data from embedded systems, and (3) Web-based software for data presentation and data management for Decision Support System (DSS) purpose. The DTMS is built to provide early warning functionality to the transformer parameter anomalies such as overload, overvoltage and blackout events. In addition, the transformer operating temperature is also an important parameter that describes the condition of the transformer in safe state, warning state or danger state. The embedded system will measure the transformer's general conditions, then using the 2.4 GHz RF communications protocol and GPRS, then it will collect and transfer data to the server via the HTTPS protocol with a programming interface compiled using the JSON format. After getting the data, DTMS will do the calculation to get recommendation of transformer optimization such as balancing, maintenance or power uprating.
