Electrical Turbine Starter Systems | Moving Towards the Oil-less Engine | Electromechanical - Parker SSD Division


Published on

Info at http://parker.com/powergen - For many years, gas turbines have been started by hydraulic or even high flow air systems. Hydraulic technology is the current prevalent method in traditional gas turbine starter applications; the seemingly more flexible and modern electrical alternatives simply could not meet the demands of the application. Today however, new technological advances have turned electrical solutions into a superior alternative to hydraulics. The solution? Parker developed its new electrical starter system that is customized to meet the demands and duty requirements of gas turbine packages. Info at http://parker.com/powergen

Electrical Turbine Starter Systems | Moving Towards the Oil-less Engine | Electromechanical - Parker SSD Division

  1. 1. Power-Gen Europe – 2013, June 4-6 - Vienna, AustriaElectrical Turbine Starter SystemMoving towards ‘The Oil-less Engine’Adrien Tenga, Division Marketing Manager, SSD DrivesEurope Division
  2. 2. Agenda• Background• Motor Technology• Drive Technology• Conclusion• Other Components of the Oil-less Engine
  3. 3. Abstract:Oil-less technology“Electric motor technology can be used toreplace new and existing hydraulic andpneumatic starter systems, reducing theneed for hydraulic and pneumaticinfrastructure.”
  4. 4. Background:Oil Leakage and Mists HazardsWider industrial trend away from using high pressure oil:• Pollution: Oil leakage and mist are environmentalpollutants• Insurance Cost: Oil leaks are a fire hazard and canincrease the cost of insurance• Health & Safety: Oil mist can reduce lung capacity,cause respiratory disease, and reduce overall workerproductivity• Disposal: New European proposals for waste oil, addedunder the European Liability Directive (ELD)“Environmental Damage protection” regulations, areincreasing oil disposal costs• Legislation: Oil mist safety is managed in ISO14001
  5. 5. Background:Application 1: Aero-derivative Turbines (<70MW)Key Requirements:Weight & Momentasserted on gearboxGas TurbineLightweight(Banana) GearboxStarter Location
  6. 6. BackgroundApplication 2: Industrial Turbines (<70MW)Key Requirements:Space Envelope relative to the Hydraulic Start SystemMinimum change from Hydraulic
  7. 7. Electric Starter TechnologyMarket requirementsGas Turbine Start Requirements Include:• Motor Weight < 70kg• Motor Torque < 700Nm• Motor Max Power < 300kW• Motor Speed <7000rpm• Operation in explosive environmentsInnovative electric motor solutions facilitate ‘like for like’hydraulic starter replacement.
