ASME B&PV Code for Hydro – Does it fit?

EME has supported the hydro power generation for over 30 years.  Prior to the widespread availability of large-scale Finite Element Analysis, generator design & fatigue calculations were performed primarily using classical “closed form” calculations, stress concentration factors, and fatigue strength correction factors.  The stator and rotor structures were considered as the fabricated components that they [...]

Grid Stability – Here’s how to achieve it

  With the addition of more renewables at an increasing pace, and the shuttering of large fossil plants, grid stability continues to be a challenge to for the US electrical grid. How should the US ISO's and RTO's respond? A highly cost effective ($/MVAR) solution is the conversion of retired generators to a synchronous condenser.  [...]

The Quarterly Engineering Problem – An Actual Case

A ventilation study was performed on a Hydro Generator as part of an uprate study.  The objective of the study was to determine if the existing ventilation would be sufficient to maintain satisfactory operating temperatures when the unit for a proposed uprate to 134 MVA from 82.5 MVA (62% increase). Combining test measurements of [...]

Generator Matters – Does Partial Discharge mean the end is near?!?

Does Partial Discharge mean the end is near!?! In this article, we examine a generator which was experiencing significant Partial Discharge (PD) and the results of testing performed to understand the expected effects on the winding life. A 150 MWe generator had experienced a tripling of the PD value on the “B” phase, over [...]
