The fulfilment of electricity needs in Aceh Province has not been evenly distributed so that the potential available natural resources continues to be explored and destroyed utilized. One high potentials province is watershed subwatershed. This study aims use Lawe-simpali subwatershed as a hydroelectric power plant meet electrical energy remote communities around Subwatershed, Province, Indones...

This paper emphasize on controlling the process variable parameters such as level and flow with real time implementation of gate control of hydroelectric power plant using Programmable Logic Controller. In this work, a programmable logic controller is used as an industrial computer playing the role of a control device and push buttons, level and flow sensors provide incoming signals to the cont...

Energy generated by the force of water in hydropower can provide a more sustainable, non-polluting alternative to fossil fuels, along with other renewable sources of energy, such as wind, solar and tidal power, bio energy and geothermal energy. Small scale hydroelectricity in Iran is well suited for “off-grid” rural electricity applications, while other renewable energy sources, such as wind, s...

Water warriors: As Brazil has already dammed and utilised its more accessible rivers, new hydroelectricity projects are planned in remote areas including the Amazon rainforests, where they endanger both ecological treasures and the livelihoods of indigenous groups. The photo shows members of the Munduruku tribe, who have recently won a rare success in blocking the fi rst of many reservoirs plan...

Transient events often account for most of the fatigue damage sustained by hydroelectric turbines during operation. Since one of these damageable events is load rejection, this paper presents a study of the dynamic response of two hydroelectric turbines during load rejection. The two turbines are similar in design and in overall measured behavior. However, we observed that the two turbine runne...

The recent increased number of black outs in the power system has been largely due to growing competition and deregulation among the power industry. Power systems are complex nonlinear systems and often exhibit low frequency electro-mechanical oscillations due to insufficient damping caused by severe operating conditions. This needs an advanced modeling and control techniques for effective cont...
