Investigation on Zero-miss Phenomenon in Shunt Reactor Compensated Long HVAC Cable for Offshore Wind Farm

Recent offshore wind farms are increasingly located between tens and hundreds of kilometers from the coastline. An important characteristic of long-distance submarine cables is their high inherent capacitance, which is typically compensated by shunt reactors. In some projects, shunt reactor installation is limited to one cable end due to responsibility boundaries between the grid operator and the wind farm owner. Owing to space constraints on offshore platforms, the offshore shunt reactor and submarine cable are often connected within the same bay and switched simultaneously using a single circuit breaker. Under such conditions, particularly when the shunt reactor compensation degree exceeds 50%, combined energization may lead to a zero-miss phenomenon, characterized by the absence of…
