Abstract

In stand-alone micro-hydro power system, water turbine will vary in speed due to the variation of consumer load. This speed variation will cause in fluctuation in both voltage and frequency output from a generator. To solve this problem, electronic load controllers were invented and used in micro-hydro power system. The objective of this paper is to monitor the electrical parameters such as voltage, current, power and frequency of electronic load controller (ELC) by using microcontroller and liquid crystal display (LCD). It explains how to monitor and sense the above parameters and isolate between the power line and microcontroller. The voltage is sensed by using the step down transformer and voltage divider circuit. The current is measured with the help of an ACS 712 current sensor. Frequency signal is obtained by using a frequency signal converter circuit. Microcontroller 16F887 and liquid crystal display are used as the main devices to monitor the above parameters according to the values obtaining from the sensing circuits.
