New features and changes introduced in this version are described here:

Electric Drives Library

The Electric Drives library is a major new addition to the SimPowerSystems library. The library is designed for engineers from many disciplines who want to incorporate easily and trustfully electric drives in the simulation of their systems.

This application library has seven typical direct current (DC) drives used in industries and transportation systems, six alternating current (AC) drives providing more efficient and versatile motors from traction to positioning devices, and shaft and speed reducer models useful for connecting to the motor a model of load made of Simulink blocks.

The Electric Drives library is accessible in the Simulink Library Browser under the SimPowerSystems / Application Libraries folder.

Note   The Simulink Accelerator mode is highly recommended to simulate models from the Electric Drives library.

Flexible AC Transmission Systems (FACTS) Library

The FACTS library provides phasor models of power-electronics based flexible AC transmission systems such as the Static Synchronous Compensator (STATCOM), the Static Synchronous Series Compensator (SSSC), the Static Var Compensator (SVC), and the Unified Power Flow Controller (UPFC). Detailed and realistic case studies illustrating shunt reactive power compensation and power conversion are provided with the FACTS library.

The FACTS library is accessible in the Simulink Library Browser under the SimPowerSystems / Application Libraries folder.

Distributed Resources (DR) Library

The DR library provides phasor models of wind turbines. It includes a model of a variable pitch wind turbine, a variable speed doubly-fed induction generator driven by a wind turbine, and a squirrel-cage induction generator driven by a variable pitch wind turbine. Case studies illustrate the steady-state and dynamic performance of wind farms connected to a distribution system.

The DR library is accessible in the Simulink Library Browser under the SimPowerSystems / Application Libraries folder.
