gráfico 13. Oscilaciones interárea en INELFE. (a) La
amortiguación de las oscilaciones mediante el afinamiento
de los controles de HVdc. (b) Validación de la respuesta
deseada de las mejoras propuestas de afinación del control
usando una simulación y réplica en tiempo real.

La precisión del simulador en tiempo real, incluidas las
réplicas de INELFE, puede ser validada y continuar siendo
evaluada al comparar los resultados de la simulación de
HIL con varias mediciones in situ. Este artículo presenta
los resultados de dos casos: 1) un paso del 20 % de energía
activa y 2) una operación de bloqueo/desbloqueo de la estación convertidora durante el funcionamiento normal.
El gráfico 10 presenta los resultados de ambos casos, en el
cual las curvas en rojo son de las réplicas y las curvas en azul
son los resultados in situ. Los resultados muestran una buena
coincidencia entre los resultados de la simulación y las mediciones in situ: las frecuencias y amplitudes de las oscilaciones
son muy cercanas. Estos resultados validan los modelos del
enlace INELFE y la red de CA que lo rodea. El gráfico 10
presenta ligeras diferencias en la amplitud del pico de tensión
de CA, que probablemente estén relacionadas con la precisión
de modelado de la disponibilidad ante cortocircuitos de la red
en el simulador en tiempo real, la cual parece un poco baja.

Investigaciones de resonancia de alta frecuencia

Se produjo un incidente inusual en el enlace INELFE de
HVdc el 22 de septiembre de 2015. Se registró una oscilación de alta frecuencia (de alrededor de 1.7  kHz) en el
PCC, seguida por el disparo de los enlaces de HVdc. El
