Pneutronic speed governor for small hydropower plants: a new application for pneumatics

Abstract This paper describes the development of a new approach for speed governors of small hydropower plants (SHPs) employing servo-pneumatic positioning system (pneutronic system). Aiming at cost reduction, easy maintenance, and obtaining an environmentally friendly product, a pneumatic system is designed for the control of wicked gates in Francis turbines to replace the conventional approach using a hydraulic system. The positioning system development is based on the non-linear modeling of the pneumatic valve and cylinder and includes a PID controller with dead zone compensation. Using a test bench corresponding to a 400 kW power plant, the model is validated and the performance requirements, according to international standards, are fully satisfied. Results are presented for a speed governor prototype installed on-site in a 35 kW Francis turbine where load rejection and step response tests were carried out. The theoretical and experimental results show that a servo-pneumatic speed governor can be used successfully for SHPs, being restricted to turbines of up to 1 MW considering only the pneumatic component costs.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
