Development and implementation of the NSP intelligent alarm processor (for power systems)

Abstract

The NSP Intelligent Alarm Processor has been in operation for four months. The operators have already begun to ask for additional functions that can make their task easier. This paper reviews the design tradeoffs, the hardware and software solutions to the implementation and the testing and performance of the IAP.

Enhancing wide-area monitoring and control with intelligent alarm handling

“…We created a cascading scenario starting with a 3-phase-to-ground fault (dead short circuit) for 100 ms near bus 2 on line [2][3][4][5] . A fault was initiated at 60 seconds and was cleared at 60.1 seconds by tripping line [2][3][4][5] . Along with the tripping of line [2][3][4][5] , 20 MW load was lost at bus 2 .…”

Situation awareness in power systems: Theory, challenges and applications

“…While the necessity of such functions has been recognized since the 1960s [68], this problem has not yet been fully solved, mainly due to the increased size, complexity and interconnectivity of modern power systems. Intelligent Alarm Processing [69], [70] provides a number of tools including alarm suppression, prioritization and reduction, which helps operators better comprehend a situation and make accurate and faster decisions [71].…”

Enhancing situation awareness in power system control centers

“…One of the most promising and widely used methods is Intelligent Alarm Processing, which has been effectively tested in operation for many years. Some examples include [28] and [29]. This method helps operators better comprehend the situation and make accurate decisions faster, as it provides a number of tools including alarm suppression, alarm prioritization, reduction of alarms on the basis of area of responsibility, and control recommendations to the operators [30].…”
