Pemeliharaan Generator & Auxiliary

Dilihat 293

DESKRIPSI Generator adalah peralatan utama pada unit pembangkit yang berfungsi menghasilkan energi listrik. Unjuk kerja generator selain dipengaruhi oleh aspek operasinya sangat dipengaruhi oleh faktor pemeliharannya. Kesalahan dalam melakukan pemeliharaan akan menyebabkan gangguan vibrasi dan menurunnya kemampuan sehingga kinerja unit turun. MATERI 1. Trouble Shooting & Maintenance Diesel Engine

7. Importance of Auxiliary Power Consumption

Degradation of Equipment Performance can be Readily Gauged From Power Consumption
Unit or Boiler Power Consumption is Monitored as % of Generation Which is just a Gross Index
Power Consumption Guarantee on Boiler Covers All Major Drives
Power Consumption should be Measured Together in a Typical Boiler Efficiency Test

8. Change in Plant Conditions with Time Increases Auxiliary Power

Air in Leakage To Boiler Gas Enclosure
Fouling of Boiler Heating Surface – Higher Dry Gas Loss Would Increase Power Consumption
Higher Draft Loss Due To Air Ingress And Ash Deposition
Air Heater Leakage/Air Ingress after APH’s
Deterioration of Turbine Steam Path Condition
Condenser Pressure/Condenser Cleanliness – Air Ingress and Extent of Tube Pluggage
Steam and Water Leaks from Drains and Vents
