When both the quantity and time thresholds are exceeded, the circuit The threshold is exceeded, the time threshold is checked and tripping action is withheld until the If not, time is incremented to observe the next measured value. Observed system variables, represented by x in the flow chart, to determine if any variableĮxceeds its threshold value. As time is incremented, the protective device checks the Usually the system is in the normal state, and the protective device is set to assume that the Such a flow chart is shown in Figure 1.2. Might be implemented in a computer control system. It is also convenient to think of this process in terms of a decision flow chart, which SUBSYNCHRONOUS RESONANCE IN POWER SYSTEMS

This essential reference work provides new and advanced concepts for understanding system performance.Ĭover Design: William T. POWER SYSTEM PROTECTION is expressly written for practicing engineers and advanced graduate-level student engineers who need a comprehensive resource on the principles of power system behavior. Reliability analysis of protective systems.His discussion shows how abnormal system behavior can be detected before damage occurs, and points to effective control action to limit system outages.Īdvance your knowledge of power system protection through a better understanding of: Anderson, a noted expert on power systems, presents an analytical and technical approach to power system protection. In a world of huge, interconnected networks that can be completely blacked out by disturbances, POWER SYSTEM PROTECTION offers you an improved understanding of the requirements necessary for prompt and accurate corrective action.
