Introduction of Hydro Turbine Governor:

Hydro turbine governor is one of the important auxiliary equipments in a hydroelectric generating set, a general term that describes one or more devices consist of realizing adaptive water-turbine and responsive control mechanism and indicators. Cording to the detection of hydroelectric generating set speed deviation to switch control into the turbine flow, water-turbine guide institutions adjust the rotate speed and output. Hydro-turbine governing system is a close loop system that consists of controller, hydraulic servo system and regulating object, usually controller and hydraulic servo system are collectively referred to as the turbine speed governors.
Functions of Hydro Turbine Governor:

* It can automatically adjust the rotating speed of hydroelectric generating, keeping them running within the allowable deviation rated speed, so as to meet the requirements of power grid frequency quality.
* It quickly makes hydroelectric generating set automatically or manually starting to adapt to the power grid load’s increase and decrease, and the needs of the normal downtime or emergency stop.
* When it runs in parallel with hydroelectric generating set in the power system, the governor can be automatically scheduled for the load distribution, and make each unit to achieve economic operation.
* It can meet the combination needs of both the paddle and impulse water turbine.
Working principle of Hydro Turbine Governor:

By comparing the rotational speed signal (frequency unit) to the power grid frequency (for a given frequency), based on its difference, the governor gives the electro-hydraulic converter an operating signal relay device on or off (command) to control the turbine water flow, and in this way achieves the regulation of turbine speed.

Found in 1958, our factory in hydropower products has continuously been one of the national strategic turbine manufacturers in China since year 1995. It has now 246,000 square meters ground area and 68,000 square meters office building area. With over 500 workers and over 200 technicians and engineers, ADDNEW's invested factory is certificated by ISO9000-2000 and CE. From the start of 2005 to the end of 2012, ADDNEW and our factory in Hunan, China have designed, manufactured and installed successfully over 170 small Hydroelectric Power Stations in Albania, Chili, Congo, India, Lithuania, Kazakhstan, Vietnam, Zambia and other overseas markets. The equipments adopted for those hydropower stations are unit-capacity from 800KW to 100MW and the total power generating capacities of each station ranging from 1600KW-200MW. All the completed stations are now maintaining their peak performance after their installations.
