Flexible DC transmission system performance
Part 1. Steady state
1 Scope
This part of GB/T 37015 specifies the requirements for the steady-state performance of flexible DC transmission systems from the perspective of safety and stability of the power system.
It includes requirements for operational adaptability, basic design requirements, operating methods, control systems, reliability and loss.
This section applies to the steady-state performance of DC back-to-back, end-to-end, multi-end systems using only modular multi-level voltage source converters.
This section can be used for DC transmission systems using current source converters.
This section can be used to guide the planning, design, construction and operation of flexible HVDC systems.
