2 SiPowerSystes Introduction Siulink library blocks dedicated to odeling, siulation and analysis of electrical circuits, electrical achines and drives, static converters and power energy systes SiPowerSystes library can be used with standard Siulink block diagras to construct various connecting eleents of a dynaic syste, and their effects on the entire power syste. 2

3 SiPowerSystes Library Uses 3 Models and siulate electrical and electronic circuits using standard sybols such as resistor, coil, capacitor or diode, thyristor, transistor etc. Provides blocks that shape different types of electrical achines (M induction achine, synchronous achine), static converters (rectifiers in bridge inverters); Provides blocks for odeling a full power energy syste (transport, distribution); llows different ethods of analysis of a syste (electrical circuit) and calculated power transfer Displays voltage and current and other paraeters in steady state

4 SiPowerSystes library contains nine libraries of electrical and electronic coponents (powerlib): 4
