“…At an exemplary project for a nationwide transmission network in North Africa [13] [14], where the Siemens SIGUARD ® DSA-system is already in use, it could be shown, that a 20 seconds transient stability contingency simulation takes about 8 seconds for simulation. Within 15 minutes (900 sec) this system is able to run more than 100 contingency simulations on a single simulation core.…”

Power transmission systems are being operated closer to their stability limits compared to twenty years ago. As a result, an increasing risk of blackouts combined with extremely high costs economically and socially is observed. To reduce this risk the personnel in the control rooms of the transmission system operators have to be assisted by a system, which assesses the dynamic state of security online. The system presented in this paper is designed to investigate the security with regards to voltage stability, transient stability and small signal oscillatory stability. New technologies of visualizing the degree of stability to non dynamic stability experts are used as well as integration in existing SCADA/EMS systems are realized. The performance of the system is sufficiently high to be employed in the online environment of the control room.

“…At the exemplary project for a nationwide transmission network in North Africa [11,12], where the Siemens DSAsystem is already in use, it could be shown, that in the time between two consecutive snapshots of the EMS-system (15 min) more than 2000 dynamic transient stability simulations with a time step of 20ms are possible using a cluster of only 10 PCs. This means that the outage of all equipment of the transmission network could be simulated, if wanted, and the dynamic stability of the network can be assessed.…”

Methods for the assessment of the dynamic network security, with regard to the installed protection system, are introduced. Currently, an accordant online system is under development together with European Universities and European Transmission System Operators. Here, the purpose is the observation of the security of the overall system, consisting of primary network and the superimposed interacting protection system including its communication.The assessment of the security of the installed protection system with its actual characteristics and settings is of special importance.

“…Of concern are the typical requirements that have to be taken into account when implementing such process into an existing environment, defined by data sources, such as the system state estimator, PMUs and SCADA system, on one side, and system control assets on the other. In particular, the common requirements put forward by the operators Australian National Electricity Bosnia and Herzegovina (NOS-BiH), and Office National de l'Electricité Morocco (ONE), which are outlined in [3]- [5] respectively are given a special attention. The following is their summary.…”

“…The credible contingencies are evaluated after system changes, periodically, or on demand. The time settings used by the operators [3]- [5] are as follows: contingency and short circuit analysis are performed every 5 minutes, transient stability calculation every 2 to 3 minutes, N-1 security is examined on a 5 minute cycle, and every time after a valid state estimation becomes available voltage security is calculated.…”
