Present day jet engines are controlled and monitored by a series of hydraulic, fueldraulic, electrical and pneumatic sub-systems known as the Full Authority Digital Engine Controller (FADEC). At the heart of the FADEC lies a centralised Electronic Engine Controller (EEC) responsible for control and safety of the wider engine system. It has long been postulated that a distributed EEC would contr...

The Francis hydro-turbine is a typical nonlinear system with coupled hydraulic, mechanical, and electrical subsystems. It difficult to understand the reasons for its operational failures, since main cause of failures due complex interaction three This paper presents an improved dynamic model hydro-turbine. study involves development hydraulic unit, given start-up emergency processes, considerat...

This research paper proposes a methodology to apply identification methods find simplified model of three different governors in single area electric power system (SAEPS). A SAEPS with governors-turbine is presented: hydraulic turbine, steam turbine and reheat turbine. In this same investigation, an analytic reduction has been performed, fifth order was found analytically, thus transfer functio...

The pitch system is notably one of the critical subsystems a wind turbine, supporting its effective control towards maximising capture and at same time protecting integrity in cases excessive loads. A pitching mechanism also responsible for operational downtime, hence reliability performance needs to be carefully evaluated so as ensure availability. This study aims derive failure rates two conf...

This article presents the methods of specifying potentiality energy recovery in turbine installations projected to hydraulic regulation heating medium Krakow District Heating System. To achieve this, creating calculations enabling indicate best places install turbines System is necessary. For this reason, a great amount work - like choosing methodology and optimal calculation program, an actual...
