The PV and QV tools are only available if you have purchased the PVQV add-on to the base Simulator package. Contact PowerWorld Corporation for details about ordering the PVQV version of Simulator.

PVQV, PowerWorld's voltage adequacy and stability assessment add-on, is used to analyze the voltage characteristics of a power system.

 

The PowerWorld Simulator (Simulator) is an interactive power system simulation package designed to simulate high voltage power system operation. In the base package, Simulator solves the power flow equations using a Newton-Raphson power flow algorithm. However, with the voltage adequacy and stability (PVQV) add-on the user can solve multiple power flow solutions in order to generate a PV curve for a particular transfer or a QV curve at a given bus.

The PVQV functionality is accessed using the PV and QV Curves (PVQV) ribbon group from the Add Ons ribbon tab. The commands available in this ribbon group are Refine Model, PV Curves, and QV Curves.

The purpose of the PVQV add-on is monitor system voltages, or other user specified parameters, as a real power transfer is increased or reactive power is injected at selected buses. The PVQV add-on uses the Simulator built-in Newton Raphson power flow algorithm to accomplish this task. After PV and QV simulations are completed, the user can choose to graph any of the monitored system parameters, designated in Quantities to Track.
