Voith Hydro introduces HyCon Go Hybrid hydraulic governor

HyCon governor

Voith Hydro presents its HyCon GoHybrid hydraulic governor, which has been in operation since the end of 2020 at a hydropower plant in Wiblingen, Germany, owned by SWU Energy GmbH (a subsidiary of Stadtwerke Ulm/Neu-Ulm GmbH).

Voith Hydro said the plant operator is convinced by the fast and uncomplicated installation and the performance of the governor.

Efficient electricity production in power plants is only guaranteed if turbine and generator output can be adjusted precisely by means of a governor. Voith has been manufacturing the required core components for almost 130 years. In 1891, the company developed the Pfarr-governor, for which a patent was filed two years later. In the 20th century, Voith made various improvements and presented new developments that form the basis for today’s automation technology, according to a press release. More than 18,500 Voith turbine governors have been delivered and installed worldwide.

Felix Lippold, product manager, describes the HyCon GoHybrid hydraulic governor as an innovation, as its use makes operations more efficient, cost-saving and ecological than before. The HyCon GoHybrid hydraulic governor combines the safety of a conventional system with the advantages of novel technologies, through which a drastic reduction of the oil content and energy consumption is achieved. The amount of oil required is reduced by up to 60% compared to conventional high-pressure units and by up to 90% compared to low-pressure units.

Due to the compact design of the hydraulic power unit (HPU), the installation effort is reduced. The pilot installation was completed within one day. Connection to the existing digital control system is simplified by a small number of interfaces. Standardized components and the reduced complexity of the system will also reduce maintenance costs for the operator.

With less than 10% of the amount of energy consumed by a conventional HPU, expectations were exceeded in terms of energy savings. Therefore, SWU Energie decided to take over the system after the test operation ending in June.

Another HyCon GoHybrid system will be commissioned in Sweden this summer.

As part of the market launch of the GoHybrid, Voith Hydro is presenting its HyCon Go governor product family, which also includes modern HPUs such as the GoActuate and digital governors such as the GoDigital. Further innovative governor technologies are under development.

The Voith Group is a global technology company in the markets for energy, oil and gas, paper, raw materials and transport and automotive. The Group Division Voith Hydro is part of the Voith Group and a supplier and partner for equipping hydropower plants.
