Penelitian ini menganalisis sistem pembebanan 6 unit Pembangkit Listrik Tenaga Diesel (PLTD) di PT. Intracawood Manufacturing, Kota Tarakan, Kalimantan Utara. PLTD digunakan untuk menggerakkan peralatan produksi yang digunakan dalam produksi bahan baku dan beban utama. PLTD ini digunakan sebagai pembangkit listrik cadangan saat sumber utama PT. PLN (Persero) Tarakan mengalami gangguan operasional atau padam. Klasifikasi 6 unit PLTD tersebut memiliki daya yang berbeda yaitu: 3 unit (G2, G6, dan G7) dengan kapasitas masing-masing 1000 KVA, 2 unit (G9 dan G11) dengan kapasitas masing-masing 1360 KVA, dan 1 unit ( G12) dengan kapasitas masing-masing 1400 KVA. Besarnya total daya yang dihasilkan oleh genset dipengaruhi oleh jumlah produksi bahan baku yang dihasilkan oleh perusahaan. Metode deskripsi analitik berdasarkan data pengukuran kualitatif pada sisi generator digunakan sebagai analisis pembebanan. Sementara itu, sistem pembangkit paralel diusulkan untuk menggunakan mekanisme tipe sinkron sebagai penyempurnaan dari metode manual. Setelah dilakukan analisa distribusi beban pada masing-masing genset, maka beban listrik yang harus ditanggung oleh masing-masing genset adalah sebesar 4,76 MW dari kapasitas mampu genset sebesar 7,14 MW atau setara dengan 67 persen daya mampu genset

“…In addition, this solution is applicable to static operation modes of power units operating in parallel for a total load (i.e., after generator synchronization has occurred). As indicated in [10], solving the generator synchronization issue is one way to increase the efficiency of AEPS operation. Moreover, the issues of generator synchronization process simulation to assess the impact of violation of synchronization conditions on the quality of the power within the AEPS network and its operation as a whole remain relevant.…”

This article focuses on studying and addressing the issue of synchronizing diesel gas generator units (DGGU) in autonomous electric power system (AEPS) in the presence of significant voltage frequency fluctuations. MATLAB models of AEPS are being developed that will enable the study of generator connection procedures while operating under a full load. Fluctuations in the rotation frequency of a diesel gas unit can be simulated by generating a realistic random procedure and adding this random signal to the control circuit. In the present study, the authors simulated the generator synchronization process in the presence of random disturbances. This simulation results indicated that the presence of random voltage frequency fluctuations and a nonzero response time of the circuit breaker (which connects the generator to the bars of the main distribution board) may violate the synchronization conditions and result in significant current surges and voltage sags at the time of synchronization. In the present work, a block diagram of the generator synchronization system is proposed that uses fuzzy logic to control the synchronization process. Software tools were developed using the methods of conceptual simulation to control the generator synchronization process; these tools represent an automated operator working station.

Introduction: This paper is the product of the investigation “Identification of relevant variables in the development of photovoltaic solar projects in Colombia” developed at the Universidad Distrital Francisco José de Caldas (UDFJC) between 2020 and 2021. Due to the increase in the number of photovoltaic energy projects in Colombia, it is necessary to quantify the level of relevance related with the factors involved in order to optimize the planning and execution processes. Methods: In this research, the Delphi methodology is applied to evaluate a set of variables selected from literature, putting them to an evaluation by a group of experts with the purpose of quantifying the relationship, under a subjective judgment, between those variables and parameters immersed in low power photovoltaic solar projects in Colombia. Together with the Delphi method, the Torgerson Model was used to quantify what experts said, in order to determine which variables are the most relevant ones to the experts. Subsequently, the validation of these answers is carried out with the application of a second evaluative stage throughout the application of structured instruments. Resultados: Luego de obtener el consenso general, se analizan los resultados con el ideal de identificar las variables que obtuvieron un mayor nivel de relevancia, en las cuales se identificaron seis variables relevantes. Conclusiones: Este trabajo muestra cómo los resultados de los procesos de investigación obtienen las variables más relevantes, siendo 6 variables en total, y se analiza su impacto. Originalidad: Aplicando el método Delphi, es posible encontrar las variables más relevantes en el desarrollo de proyectos solares fotovoltaicos de baja potencia en Colombia, haciendo de este trabajo un elemento importante en el avance de las energías renovables. Limitación: No se logró una muestra masiva de resultados por la dificultad de contactar a los profesionales adecuados en el área analizada.
