Abstract

The generator is the primary component in electricity generation and requires a protection system from internal and external interference that occurs. This study considers how to improve the performance of relays in power plants. A model of a generator that is executed in a fault condition to reset the protective equipment, namely Reverse Power Relay (RPR). The study is intended to model the state of internal and external fault on the generator by applying a working principle of RPR. The model is designed to anticipate the actual fault in the generator. The simulation results obtained output such as; active power, current and time delay relay. The RPR reset of the generator system is applied to the generator in Riau Power. The RPR is installed on the generator is -612 kW, equivalent to 30%, the relay delay time is 0.2 seconds. Based on standardization, the return of power reaches a maximum of -12.66 MW, which is captured 50% with a maximum replacement of 30 seconds. Results of the RPR simulation have been validated with the IEEE standard at a time delay that corresponds to the percentage of reverse power settings installed at 6% and a time delay of 0.6%. Finally, to maximize the protection system on the generator, adjust 50% to 95% of the installed settings. It can be said that the system is able to increase generator protection and minimize the impact of internal or external fault.

Abstract

This paper presents photovoltaic system as a stand-alone electric power plant in the renewable energy development.  To maximize these stand-alone generators, it is necessary to design photovoltaic modeling to produce energy and maximum power.  The problems that exist in the design of PV systems are PV configuration, battery size, and the maximum power system. Therefore, this research will be proposed modeling Matlab/Simulink based PV system. The contribution of this research can provide various characteristics of the photovoltaic system with a capacity of 100 Wp.  This modeling is designed using Matlab/Simulink software.  The data generated from this simulation will provide a good reference for designing the stand-alone generators in the future.

Abstract

A power transformer is an electrical machine that converts electrical power at different voltage levels. Faults, occur in power transformers, inhibit electrical power distribution to the consumer. Protection, therefore, of the power transformers is essential in power systems reliability. The power system can be reliable if the protection devices work well when there is a fault. A hybrid intelligent technique, which is a combination of Artificial Neural Network (ANN) and Fuzzy known as Adaptive Neuro-Fuzzy Inference Systems (ANFIS), was used in this research. The objective of this paper is the simulation of differential relays as a protection device on power transformers using Matlab/Simulink. Performance of differential relays for power transformers protection is carried out with internal and external fault scenarios. The input data were classified into three different input for ANFIS such as internal and external 1, internal and external 2, internal, external 1, and external 2, respectively. The error results of ANFIS training for the type of fault internal and external 1 is 9.46*10-7, and types of fault internal and external 2 is 1.09*10-6 internal, external 1 and external 2 are 8.59*10-7. The results obtained from the simulation were accurate and shows that the ANFIS technique is an efficient method that gives less error and a great value. Finally, the technique can minimize faults with power transformers. Finally, to prove this method can reduce faults in the power transformer, the assess of this model has been carried out through the RMSE that has been generated which is zero.

Abstract

Sistem daya listrik terdiri dari pembangkitan, sistem transmisi, sistem distribusi, sistem proteksi dan beban. Sistem transmisi merupakan elemen yang digunakan sebagai objek simulasi ketika terjadi gangguan di saluran transmisi. Sedangkan, untuk sistem proteksi menggunakan pengontrolan secara digital untuk mengatasi kesalahan pada perhitungan setting impedansi rele jarak.  Pada sistem transmisi saat terjadi gangguan dengan mendapatkan informasi rele jarak dan Circuit Breaker (CB) yang akan digunakan sebagai data untuk menjalankan teknik cerdas. Oleh karena itu, dalam artikel ini akan diusulkan satu metode teknik cerdas yang merupakan model komputasi. Teknik cerdas yang akan digunakan ini adalah teknik Jaringan Syaraf Tiruan (JST) berbasiskan  Back Propagation (BP). Pelatihan JST-BP ini akan dijalankan proses pelatihan untuk memecahkan permasalahan identifikasi lokasi gangguan di sistem transmisi daya listrik.  Hasil keluaran yang diharapkan memberikan koreksi galat yang kecil dan akan lebih mendekati nilai yang baik. Dan akhirnya, dengan teknik JST-BP ini diharapkan dapat mengidentifikasi lokasi gangguan secara tepat dan benar.

Abstract

This study is intended to design a system connected to the Distributed Generation (DG) sourced from solar cells, using Matlab/Simulink. A Phasor Measurement Unit (PMU) is installed in the DG system to monitor the phasor voltage and current. Furthermore, the system comprises four buses with two 20 kV load voltages, two amplifying transformers, and four transmission lines. The DG's role is to keep the power supply to the load stable and improve power efficiency by reducing power losses on the network. However, in this network, the DG increases the current on each bus. Thus, affecting voltage increase on each bus, consequently increasing the stress experienced by both loads. The DG-connected system simulation on PMU-3 & PMU-4 has a minute error value of 0.02% and is slightly higher than the unconnected simulation. This comparison also shows the positive sequence values of the phasor currents as well as phasor voltages before and after the DG connection. The DG system connected to the PMU has monitored voltage and current for PLN and DG systems based on the simulation results. Therefore, installing the DG can increase the line voltage, especially on the load.
