Flexible Wide Area Monitoring, Protection and Control Applications in Future Power Networks

چکیده
The complexity of future power networks and the expected high level of uncertainties in these networks might radically affect the required security and reliability of their operation. Wide-Area Monitoring, Protection and Control (WAMPAC) involves the use of system-wide information and the communication of selected local information to a remote location to counteract the propagation of large disturbances and reducing by this the probability of potential catastrophic blackouts. Synchronized Measurement Technology (SMT) is an important element and enabler of WAMPAC. It is expected that WAMPAC systems will in the future generally improve the reliability and security of energy production, transmission and distribution, particularly in power networks with a high level of operational uncertainties. In the paper several key protection and control applications are described and discussed. A strategy for developing a WAMPAC system in the UK is given as well.

Load-Frequency Control: a GA based Bayesian Networks Multi-agent System
Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...
متن کاملA Fast Voltage Collapse Detection and Prevention Based on Wide Area Monitoring and Control
Voltage stability is one of the most important factors in maintaining reliable operation of power systems. When a disturbance occurs in the power system, it usually causes instabilities and sometimes leads to voltage collapse (VC). To avoid such problems, a novel approach called Vector Analysis (VA) is proposed that exploits a new instability detection index to provide wide area voltage stabili...

To date, synchronized phasor measurements have been used mainly for power system model validation, post-event analysis, real-time display, and other similar activities. However, synchrophasors have a greater potential than monitoring and visualization. Synchrophasors will increasingly contribute to the reliable and economical operation of power systems as real-time control and protection scheme...

Probably the most significant development in the future is the evolution of the EMS to a more intelligent, automated system to analyze, predict and prevent events leading to a total system collapse. The transition to a highly automated system is possible in part by the recent advances in communication technology, hardware architecture, web services and installation of synchronized phasor measur...
