Foreword (1/3)• In 1987, the Kraftwerke Mainz-Wiesbaden,

Germany (KMW AG), became the first official andregistered user of the DIgSILENT software.

• The fact that after some 27 years, KMW AG’sPowerFactory installations are still maintained is adefinite indicator that any possible initial doubt wasunwarranted.

• In fact, over the past several years, the user basehas grown considerably, establishing a large usercommunity of highly qualified, experienced andcreative users.

Foreword (2/3)• PowerFactory extends this flexibility even further via the

provision of powerful scripting tools allowing the userto develop specific applications according to individualneeds.

• This first issue of the PowerFactory Applications forPower System Analysis serves as an impressivedemonstration of the wide range of power systemanalysis applications that can be handled by thePowerFactory software.

• In addition, the solutions described for a certain analysistask will motivate and help other users to make use ofthe software’s flexibility and give guidance regardingpossible solution options.

Foreword (3/3)

• “We thank all authors who have contributed to this

book, initiated by Francisco Gonzalez-Longatt and

José Luis Rueda, for sharing their valuable

PowerFactory experiences and solutions”.

• The topics presented are also of great interest to the

PowerFactory development team in their endeavours

to optimize further releases and develop even more

flexible functions.

Real-Time simulator

• Hydro-Québec develops HYPERSIM: a real-time

simulator

– Develop, improve and assess new protection and control

concepts

– Optimize the operation and the maintenance power

systems

– Decrease the time required to commission protection

relays and control systems (FACTS, HVDC, SVC, etc..)

– Reproduce events that occurred in the power system by

using the actual protection and control systems

Introduction: Interfacing

• Various possibilities exist to interface the power

system model and simulation engine of

PowerFactory.

• These interfaces open applications for co-

simulation, real-time simulation for controller

hardware-in-the-loop (HIL) set-ups or automation

and control of simulation.
