Real-time power system analysis and security monitoring by WAMPAC systems

Abstract

The outline of this paper is to implement real-time analysis and security monitoring in the smart power system. Security is the ability of the power system to withstand contingencies. The principal role of Wide Area Monitoring, Protection and Control (WAMPAC) system is to maintain a secure system state, i.e. the system that can withstand each specified contingency. The advanced WAM system uses real-time measurements to monitor system status and hence determines whether or not it is secure. The WAMPAC system is used to deploy proper control actions on load, transmission and generation in a wide time frame from fast protection systems to slower control of generators. This paper also explores the challenges and opportunities to implement online system analysis capability in order to monitor system security and stability indices. Therefore, the implemented hardware/software setup for monitoring and analyzing system in real-time format will be presented by the online results available with real-time software. Online load flow and contingency results aim to proper security monitoring of power system in wide area which is useful for most application such as system remedial actions.

Empirical Development of a Trusted Sensing Base for Power System Infrastructures

“…The test-bed provides a great platform at the laboratory scale to help test and verify new operation, protection, control, and investigate techniques [18]- [20].…”

Web-Enabled Generalized Architectural Model for Online Power System Analysis

“…The basic architecture of Web-based online real time integrated information system has been analyzed (Choi et al, 2011). The power system simulation package with various analysis distributed in a clustered environment has been modeled (Salehi et al, 2011). The package is completely web based and platform independent.…”

“…The package is completely web based and platform independent. An experimental illustration for on-line security analysis is carried out (Salehi et al, 2011). It is reported that the analysis could be executed in lesser period of time even for large power system.…”

Simulation approach to reliability analysis of WAMPAC system

“…These PMUs are placed at selected primary substations to obtain measurements by sensors and to execute control actions through actuators. The PMUs are able to report their measurement values upwards to a hierarchy of substations for phasor data concentrators (PDCs), then to network control centres through available communication networks [9]. A centralized control unit, often located in a control centre, make decisions and sends control signals back to the actuators through remote terminal units (RTUs) or PMUs.…”
