“…That is the only way, the danger of cascading outages, as occurred at beginning blackouts, can be identified. A DSA-system, for example the Siemens system SIGUARD ® DSA, must be able to not only assess the dynamic state of the system, but also to determine, rate and visualize the margins to critical states of the system [10]. To do so, an interconnection to existing control systems is essential, in order to provide continuous snapshots of the actual, quasi-steady-state condition of the system as a basis for the dynamic security assessment [11].…”

Power transmission systems are being operated closer to their stability limits compared to twenty years ago. As a result, an increasing risk of blackouts combined with extremely high costs economically and socially is observed. To reduce this risk the personnel in the control rooms of the transmission system operators have to be assisted by a system, which assesses the dynamic state of security online. The system presented in this paper is designed to investigate the security with regards to voltage stability, transient stability and small signal oscillatory stability. New technologies of visualizing the degree of stability to non dynamic stability experts are used as well as integration in existing SCADA/EMS systems are realized. The performance of the system is sufficiently high to be employed in the online environment of the control room.

Methods for the assessment of the dynamic network security, with regard to the installed protection system, are introduced. Currently, an accordant online system is under development together with European Universities and European Transmission System Operators. Here, the purpose is the observation of the security of the overall system, consisting of primary network and the superimposed interacting protection system including its communication.The assessment of the security of the installed protection system with its actual characteristics and settings is of special importance.

“…Los Sistemas Eléctricos de Potencia (SEP) han sido operados cada vez más cerca de sus límites físicos debido, por ejemplo, a la inclusión de principios de desregularización en el mercado eléctrico, la interconexión con sistemas regionales, la diversificación de las fuentes primarias de energía e incluso nuevas restricciones de tipo ambiental. Bajo estas condiciones, ciertas perturbaciones imprevistas podrían causar la violación de los límites de seguridad del SEP, poniéndolo en riesgo de un eventual colapso total o parcial [1], [2]. En este sentido, la supervisión de la seguridad estática y dinámica del SEP en tiempo real presenta un rol fundamental dentro de las aplicaciones empleadas en los Centros de Control.…”

La diferencia angular de los voltajes de barra de un sistema eléctrico de potencia (SEP) es una medida directa del estado de congestión del sistema. En este sentido, su continuo monitoreo brinda al operador una señal de alerta de posibles estados de congestión del SEP, cuando las diferencias angulares superan límites de seguridad pre-establecidos (límites de estabilidad estática de ángulo). Con el desarrollo de la tecnología de medición sincrofasorial, el monitoreo de la diferencia angular ha adquirido un nuevo enfoque, puesto que se independiza del estimador de estado, lográndose mayor robustez y rapidez. El operador del Sistema Nacional Interconectado, CENACE, dispone actualmente de un sistema de medición sincrofasorial, administrado por la plataforma WAProtector. Este software dispone de una aplicación que permite el monitoreo de la diferencia angular de voltajes de barra del sistema, usando técnicas de visualización avanzada. Este artículo presenta una introducción a la tecnología de medición sincrofasorial, así como una reseña del sistema WAMS del CENACE. Posteriormente, una propuesta metodológica para determinar los límites de estabilidad estática de ángulo, es presentada. Estos límites servirán como base referencial para el monitoreo en tiempo real.
