Abstract— One of the development of technological innovations in the field of control systems in all aspects of life is needed to maintain the stability of the work of a system, PID control to maintain the speed of water flow in the supply pipe in order to maintain the rotating speed of turbines Micro Hydro Power Plants (PLTMH) is very necessary because to maintain the generator rotational speed remains stable. To maintain the stability of the water flow, a sluice gate is needed to regulate the flow of water that comes out of the reservoir to the stockpile, the sluice is called a valve that can be controlled with a microcontroller that will open and close in accordance with the data value of the Water Flow Sensor attached to the pipe. Simulation of Water Flow Sensor with PID control is used to simulate the MHP system with PID control by comparing the output if the PID value is changed.

Micro-hydro power plants (μHPPs) are a major energy source in grid-isolated zones because they do not require reservoirs and dams to be built. μHPPs operate in a standalone mode, but a continuously varying load generates voltage unbalances and frequency fluctuations which can cause long-term damage to plant components. One method of frequency regulation is the use of alternating current-alternating current (AC-AC) converters as an electronic load controller (ELC). The disadvantage of AC-AC converters is reactive power consumption with the associated decrease in both the power factor and the capacity of the alternator to deliver current. To avoid this disadvantage, we proposed two rectifier topologies combined with symmetrical switching. However, the performance of the frequency regulation loop with each topology remains unknown. Therefore, the objective of this work was to evaluate the performance of the frequency regulation loop when each topology, with a symmetrical switching form, was inserted. A MATLAB® model was implemented to simulate the frequency loop. The results from a μHPP case study in a small Cuban rural community called ‘Los Gallegos’ showed that the performance of the frequency regulation loop using the proposed topologies satisfied the standard frequency regulation and increased both the power factor and current delivery capabilities of the alternator.

Land degradation on the upstream of watershed will affect hydrology condition in a way that it will disrupt the sustainability of its existing micro hydro. The purpose of this study is to evaluate micro hydro power plant in central Java toward sustainability against hydrology condition of watershed. This study is using River Regime Coefficient (RRC) approach where hydrology of watershed with coefficient value less than 50 is classified as non-critical, between 50 and 120 is moderate and more than 120 is critical. Result of the study that was done on 33 micro hydro power plants scattered on 9 watersheds is showing that there are 2 power plants on 2 watersheds have hydrology condition in non-critical status (9.09%), 1 power plant on 1 watershed is in between critical and non-critical status (3.03%), 21 power plants on 3 watersheds are in between critical and moderate status (63.64%), 8 power plants on 6 watersheds are in critical status (21.21%) and 1 power plant on 1 watershed is in between moderate and critical status (3.03%).

The paper is a result of research at the Mechanical Engineering Faculty in Podgorica and represents the aspiration of authors to combine scientific and technical experience in order to achieve improvement in a real system. It is a complex system of lock chambers in a hydroelectric power plant. Based on a detailed analysis of the initial state, through the process modeling of complex real system, the authors identify possible areas where the intervening and applying modern systems with greater flexibility is necessary to achieve higher levels of automation. Also, proposed in the paper are measures for ensuring the security of information that rise system performance to a higher level compared to the competition and create an advantage in the global market.
