A recent major refurbishment of the water wheel gave scope for implementing the latest hydraulic technology to improve what was the trust’s first and largest hydro-electric scheme, generating electricity for the visitor centre and to feed the National ...
In 2004, Great Bay Hydro Corporation acquired four generating facilities in Vermont, including the West Charleston Hydro plant which had been out of operation and abandoned for a number of years. ...
This marks significant progress considering coal generation was more than twice that of wind, solar and biomass just five years ago, with these three energy sources providing 12% more electricity in 2017 than in 2016. ...
Such factors greatly discourage the consumers to shift out of fuel consumption and on to the green power generation alternatives. The biggest concern about utilization of renewable sources for energy production is that they fail to generate the massive amount of electricity as that produced by their non-renewable counterparts like coal. Power ...
This paper presents power estimation and reliability evaluation of the micro hydro power generation system based on municipal waste water. Self–excited induction generator was used in the developed power plant, situated at IIT (BHU) campus, Varanasi, India. The hydro potential of the waste water flowing through sewage system of ...
Abstract This article describes a specific instrument for detection of excitation winding shorted turns in hydro generators, developed in Koncar - Electrical Engineering Institute Inc., called Hydro generator Winding Fault Detection (HO WFD). ...
This paper presents a radical methodology to find the solution of optimal short-term hydrothermal generation scheduling problem using modified invasive weed optimisation algorithm (MIWOA). ...
This paper presents a new configuration of a voltage and frequency controller for a stand alone pico hydro power generating system employing an Isolated Asynchronous Generator (IAG). ...
So visionaries such as William Tianming Li, VP - Asia Power, Chang Yeol Lee, Head of Distribution– KEPCO, Myung-Key Lee, Manager General, - Korea Hydro and Nuclear Power, Ario Senoaji, VP Alternative/Renewable Energy - PLN and Ashok Sethy, VP – TaTa Power, agreed to attend this week in Sentosa to discuss unified measures to ensure renewable energy solutions for ...
This paper presents a novel configuration of a voltage and frequency (VF) controller for a stand-alone pico hydro power generating system employing an asynchronous generator (IAG). ...
Abstract The paper describes main reasons for refurbishment of hydro power plants and summarizes the most frequent works during refurbishment. ...
Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. ...
Nearly 700 cities in China with an urban population of more than 100,000 all need high levels of basic infrastructure investment, including electricity, housing, transportation, water and wastewater. At the start of 2000, hydro generation capacity in China stood at 73,000 megawatts (MW). By 2005 the total was 95,300 MW, and this capacity is planned to increase ...
The paper describes models of the local network operation of the hydraulic turbine-generator unit. Two different models are proposed. They describe the dynamic behaviour of a system in which the unit is connected to an equivalent system. A nonlinear model of the interconnection to an equivalent power system is considered. An optimal controller for load disturbance rejection in water turbine speed ...
Applying these technologies to small hydro automation, affordable multifunctional distributed processing solutions is now a commercial reality. ...
This paper presents reactive power control of isolated wind-diesel-micro-hydro hybrid power system for realistic load disturbance using matlab/simulink. ...
Salient issues associated with the connection of hydropower distributed generation (HPDG) into distribution networks include operation and voltage regulation, grid connection and control interaction, anti-islanding protection and islanding operation, and operation of protective devices. ...
Induction generators are one of the most popular generators for micro hydro systems. Three phase generators are often used even though only a single phase supply is needed. ...
The paper discusses simulated control cases of the wound rotor self-excited induction generator WRSEIG. The generator external controller is designed to regulate the output voltage and frequency for constant or variable speed operation of the prime mover and has the inherent capability of protecting the load from short circuit, which permits voltage collapse ...
When the power sector is based on cheap hydro-based generation capacity, new projects for electricity generation tend to have higher costs than the installed capacity. ...
