THEORY:
The regulation of a 3-phase alternator may be predetermined by conducting the Open Circuit (OC) and the Sort Circuit (SC) tests. The methods employed for determination of regulation are EMF or synchronous impedance method, MMF or Ampere Turns method and the ZPF or Potier triangle method. In this experiment, the EMF and MMF methods are used. The OC and SC graphs are plotted from the two tests. The synchronous impedance is found from the OC test. The regulation is then determined at different power factors by ....etc

a novel night-time application of a photovoltaic (PV) solar power farm bidirectional inverter as a battery charger, is presented. It is shown that a combination of PV solar farm and storage batteries can be advantageous in a distribution system having wind farm in close vicinity to the solar farm. Under such a condition, the PV solar farm inverter can regulate the grid voltage (if allowed by the code) by charging/ discharging the batteries as well as provide better asset utilization and return on investments. The PV solar farm inverter is opera ....etc

Voltage Sags and the Response of a Synchronous
Distributed Generator: A Case Study
Edward R. (Randy) Collins, Senior Member, IEE, and Jian Jiang, Student Member, IEE
Abstract
The dynamic behavior of a synchronous distributed
generator connected to a distribution system during fault conditions
is studied. A fault on an actual system was found to have
a sag that was extended after the fault was cleared. It is shown
that the combination of the generator and the load on the system
contributes to th ....etc
