Circular Voltage Profile

Networks with large numbers of nodes

Analyze the voltage profile and network topology of large networks. The entire network or a specific area can be visualized using different graphs.

Line Power Flow

Active and reactive power flow

Study the flow of active and reactive power in the system. Transformer taps and switched shunts can be adjusted during power flow iterations to control voltage and reactive power.

Capability Curve

System operating point

Easily compare different scenarios and analyze how changing equipment parameters affect the operating point of the system.
