AC/DC Protection Coordination
Comprehensive AC and DC protection coordination studies including AC protection settings validation with NETOMAC and DC protection coordination for HVDC SMP, Bipolar, and Multi-Terminal configurations.
What is AC/DC Protection Coordination?
AC/DC Protection Coordination involves the systematic design and validation of protection schemes for both alternating current and direct current power systems. This critical engineering discipline ensures that protection devices operate in a coordinated manner to isolate faults quickly while maintaining system stability and minimizing the impact on healthy parts of the network.
Our protection coordination services encompass comprehensive studies for AC systems using advanced tools like NETOMAC, as well as specialized DC protection coordination for various HVDC configurations including Symmetric Monopole (SMP), Bipolar, and Multi-Terminal (MT) systems.
