More and more often series compensation, non-standard generation and power electronic devices co-exist in a vicinity of EHV transmission lines. A typical scenario is a relatively long transmission line already with elements of HVDC and/or series-compensation, interconnected to a new wind farm with significant capacity driven by non-standard machines. In some cases single-pole tripping is applied in...
Line protection in breaker-and-a-half configurations requires main protection functions to respond to the sum of the two currents. This concerns many protection functions particularly when sensitive settings are applied and/or significant Ct saturation occurs. If the remote system is relatively weak, the current supplied through the line towards a close-in reverse fault on the breaker-and-a-half terminal...
