Capacidades únicas disponibles con la
HVdc
Existen muchas razones para el desarrollo de proyectos
de HVdc que llevaron a considerar el proyecto de LCC-HVdc en la República de Corea. El proyecto propuesto
conecta grandes plantas de energía (incluida la generación de energía nuclear) con centros de carga distantes,
mantiene la disponibilidad ante cortocircuitos dentro de
niveles aceptables, requiere una mínima servidumbre de
paso y utiliza una modulación de energía rápida y demás
controles para minimizar los efectos adversos de contingencias con un impacto extremadamente alto. El proyecto
de LCC-HVdc requirió múltiples estudios de viabilidad
para garantizar que pudiera brindar una solución a los
muchos problemas complejos presentados por el sistema
en la República de Corea.
Para cumplir con el estándar de rendimiento de confiabilidad cuando ocurre una contingencia crítica de la línea
de 765 kV, el proyecto utiliza una sofisticada estrategia de
control que incrementa rápidamente la producción de energía CC en combinación con otros controles y un SPS. La
modulación de energía de HVdc es una aplicación común en
la industria, en especial para reducir el sistema de HVdc a
fin de proteger los equipos en respuesta a una contingencia.
Sin embargo, este proyecto también utiliza una capacidad
de sobrecarga para el sistema de HVdc en coordinación con
los controles del sistema de transmisión de corriente alterna
flexible (FACTS) para minimizar el rechazo de la generación. Las contingencias críticas aceleran los generadores en

el este, pero permanecen estables cuando las transferencias
de HVdc al oeste aumentan repentinamente, lo que proporciona una solución rentable para estos eventos raros del
sistema. Al subir la HVdc, también se alivian las posibles
sobrecargas térmicas de otras instalaciones de transmisión.
El plan aún requiere acciones de un SPS para la reconfiguración del sistema de transmisión de CA, el rechazo de
algunas generaciones y la provisión de un soporte de energía reactiva.

Estudio de viabilidad combinado
de LCC-HVdc y FACTS
El estudio de este proyecto de HVdc comenzó en 2013 con un
estudio de viabilidad convencional para estimar el tamaño y
las ubicaciones de las terminales. La tasa de cortocircuito
(scr) y la scr efectiva (Escr) proporcionan índices críticos que
se utilizan para comparar la fortaleza de un sistema de CA
con opciones de expansión HVdc aceptables. Los niveles de
cortocircuito y de scr se examinaron en busca de las interrupciones de transmisión más severas para las condiciones
del caso base con hasta dos generadores normalmente fuera
de servicio.
El análisis con la utilización de una herramienta de análisis de estabilidad transitoria (TSA) evaluó varios escenarios
de funcionamiento creíbles a fin de identificar los puntos de
conexión óptimos para las estaciones de HVdc. Se identificaron cinco ubicaciones en las líneas de transmisión de 765 kV,
y se simularon como el peor caso de fallas de barras trifásicas en los estudios. Sin embargo, los ingenieros de la KEPCO
llevaron a cabo el TSA de todas las contingencias creíbles
en todo el sistema y, específicamente, en los terminales de
HVdc. Todos los resultados para un plan determinado deben
