Question by wilhem: 100wt energy saving bulb in a socket rated for a 60wt standard bulb? My standard ceiling light sockets suggest that I use standard 60 watt bulbs. The cold light of a 60 watt flourescent bulb is just not enough light. Can I use a 75 or 100 watt flourescent bulbs instead. ——————————————

Review by W. James D. Easton for Grid Integration of Wind Energy Conversion Systems
Rating:
This should be compared to Thomas Ackermann’s “Wind Power in Power Systems.”
If I purchased only one, it would be Ackermann, which I think is generally more comprehensive (and bigger). That said, I would need to supplement it with a lot of specific engineering data if I wanted to do any particular analysis.
Heier gets much more into lower level engineering details. Ackermann, looks more at a general systems and regulatory environment perspective.
Both books are very good and generally easy to read, providing good overviews of “current” practise.

The book is great. You can find the basic theory and description of the control systems for wind turbines applications. I just wait to have the second edition in my hands.
