The McLeod Dam is one of six dams on the Moira River in Belleville, Ontario, Canada, owned and operated by the Quinte Conservation Association. This dam was constructed in the late 1970’s for the primary purpose of ice and flood control. In 2008, the dam was retrofitted for the secondary purpose of power generation. CHC supplied a water-to-wire equipment package consisting of two (2) ...
Located on the Stanislaus River in central California, the Tulloch Dam operates two vertical Francis units for a combined output of 18 MW. Commissioned in 2012, CHC provided an additional 1650 mm conventional Kaplan turbine-generator set which was added on the low level outlet of the dam, and which produces over 6.7 MW of additional power using the water that spills over the dam. The complete ...
Located on the Androscoggin River in Maine, the Livermore Falls hydro project required the installation of a turbine unit that would meet government minimum flow requirements on the river. CHC provided a water-to-wire equipment package which included a 1500 mm axial flow propeller turbine along with generator, hydraulic power unit, switchgear and controls to comply with the minimum flow ...
The Canal Boba and Las Barias Hydro projects were developed by the local Dominican utility with the Montreal engineering firm of Dessau Soprin. CHC provided two identical water-to-wire equipment packages, each including a 1250 mm axial flow Kaplan turbine, 900 kW/450 RPM synchronous generator hydraulic power unit and switchgear, controls and protection package. The projects were commissioned ...
The Higley generating station was built in 1913 and is located on the Raquette River in the State of New York. The original plant contained threeFrancis turbines producing just over 4 MW of power. In 2002, a new plant was constructed next to the existing plant, for which CHC provided four 1500 mm axial flow turbines – two propeller and two Kaplan. The existing units remained in service ...
A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project's firm energy yield. ...
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). The proposed controller is an Electronic Load Controller (ELC), which consists of a three leg IGBT (Insulated Gate Bipolar Junction Transistor) based Voltage Source Converter (VSC), a DC chopper and an auxiliary load ...
Small power hydrostations, being devoid of these problems have become a viable alternative. Control systems and governors are key components of small hydropower stations as they have to supply stable power while accommodating varying load conditions and erratic water flows. ...
A new scheme is proposed for the speed control of hydro turbines. Power can be controlled by controlling the rotary motion of the spear valve or linear motion of the sluice gate. In this paper, necessity for speed control, various function of governors, types, speed regulation of micro-hydroelectric power plants, functional block diagram of power generation and control system general models for ...
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. ...
The introduction and significant momentum on diffusion of wind power as a new technology for energy production involve a push for changing the institutional framework in the energy sector. The introduction of hydro (electric) power technology and the following institutional change process may be compared to the introduction of wind power 90 years later. In this paper, the main focus is on the ...
