Trends in power system protection and control

Proceedings of the 32nd Annual Hawaii International Conference on Systems Sciences. 1999. HICSS-32. Abstracts and CD-ROM of Full Papers, 2001
Abstract As a consequence of deregulation, competition and problems in securing capital outlays for expansion of the infrastructure, modern power systems are operating at ever-smaller capacity and stability margins. Traditional entities involved in securing adequate protection and control for the system may soon become inadequate, and the emergence ...

Diagnosis of Power System Protection

2006
Power systems are naturally exposed to several fault conditions, namely short-circuits. Automatic protection and control systems are responsible for selective tripping of faulted devices and their subsequent reconnection. An application to automatically diagnosing abnormal conditions in power distribution network substations is described in this ...

Safety and Reliability Analysis of Protection Systems for Power Systems

IFAC Proceedings Volumes, 2006
Abstract This paper addresses the problem of risk analysis of protection systems and protection scheme of transmission grid. According to IEC 61508, a hybrid model has been developed supporting the analysis of protection systems. The use of analytic models in risk analysis of the elements of system protection scheme allows evaluating the security ...

AN EXPERT SYSTEM USED IN POWER SYSTEM PROTECTION

IFAC Proceedings Volumes, 1989
Abstract An expert system has been developed for recording and modelling knowledge of power engineering experts in the domain of protection coordination for industrial power systems. This paper describes a methodology used to isolate, identify and codify the knowledge and steps used by design experts when taking an initial design specification ...

Integrated protection of power systems

2006 IEEE Power Engineering Society General Meeting, 2006
This paper reports on the development of integrated protection for power system. The concept of integrated protection is introduced, in which a centralized protection system (or relay) provides the protection of multiple power plant or a substation.
