I am a member of the Working Group developing IEEE P1547.2 Draft Application Guide for IEEE 1547 Standard for Interconnecting Distributed Resources with Electric Power Systems. We are including a general description of power systems. This information should be helpful since the siting and...
What remediation techniques are available to manage the 2nd harmonics being injected into the AC supply by a three pulse rectifier for a DC motor? Reportedly, the total harmonics on this service exceeds the IEEE 519 limits. The harmonics are predominantly 2nd, 3rd and 5th. If the load...
What are the decision making advantages / disadvantages for choosing induction or synchronous motors for industrial applications such as paper mill refiners? The sizes are 1,000 to 3,000 HP, and the voltage is 2.4-kV.
The mill is served by a 33 MVA 115/12.47-kV transformer, and the expansion...
The situation I have is a 24.94-kV four wire grounded system normally serving load through a 24.94/12.47-kV delta/wye stepdown. Both the 12.47-kV and the 24.94-kV are four wire grounded wye systems. There is a desire to reverse the flow and serve several customers on the 24.94-kV side from a...
