This paper presents an experience in the design and implementation of the condition-monitoring system for the synchronous generators whose primary purpose is to record data for the identification of the capability limits of the P–Q diagram of three generators in hydro power-plant. Paper presents details about the monitoring system, the underlying theory of the identification of the synchronous generator model with a focus on the calculation of the capability limits in the P–Q diagram. Furthermore, a computationally efficient method for the representation of capability limits suitable for the implementation within the industrial automation and control system of the power-plant is described in detail. Finally, the capability diagrams for three generators were implemented in the power-plant supervisory control and data acquisition system (SCADA) system.

The paper ‘Performance Analysis of Microcontroller based Electronic Load Controller’ is an approach for design, fabrication and performance analysis of microcontroller based ELC for 300 Watt Pico hydro controller. Electronic Load Controller (ELC) is an approach for regulating total power in the system with Pico-hydro power plant. The paper presents a unique method to maintain the system performance by regulating the generated power. The system voltage and current is measured by microcontroller to calculate the consumer power. Based upon the consumer power the dump power is varied accordingly. The performance analysis of ELC unit was done with power source from Nepal Electricity Authority (NEA) grid line as well as with separately excited induction generator under various loading conditions. The different resistive, capacitive and inductive loads were taken into consideration and the performance of the system based on voltage, current and power profiles were obtained.Kathmandu University Journal of Science, Engineering and TechnologyVol. 13, No. 1, 2017, 20-35

This paper presents the results of research on a new schematic generator load controller simulation, namely an electronic load controller based on a dimmer circuit and a stepper motor for a small-scale 5 kW micro-hydro. The load controller is built from a dimmer circuit and a stepper motor with program control using Matlab software, and the PPI 8255 interface device. Using a dimmer circuit built from diac, triac, a variable resistor (pot), and capacitor components. As well as using a 28BYJ-48 stepper motor. Simulation is made to determine the performance of the load controller in controlling the distribution of power to the ballast load when the generator supplies power to consumers less than the full load of the generator. By using the simulation data of 45 variations of the consumer load sample, the result is that there are only 4 samples where the load controller is not working well. For the 4 samples, the generator was loaded beyond its full load tolerance limit (full load tolerance of 5kW ± 5 %). Overall, based on the simulation results, it can be said that the generator load controllers tested in this study have good performance. HIGHLIGHTS Methods and power electronic configurations used in electronic load controllers for micro-hydropower plants from 1980 until now. In the future, the use of low-power micro hydro and pico hydro power plants is also in great demand, especially for rural areas The utilization of micro-hydro in Indonesia, especially low-power micro-hydro, has been utilized by the community in Bulukumba Regency, South Sulawesi Province. A 5 kW generator has been operated in Katimbang Village, Borong Rappoa District, Kindang Regency, Bulukumba Regency, South Sulawesi Province to distribute electrical energy to 15 households This research proposes a new electronic load control scheme for a simple and inexpensive 5 kW micro-hydro power plant, namely a dimmer circuit and stepper motor-based generator load controller. With the consideration that the main components that make up this controller are not expensive GRAPHICAL ABSTRACT
