Optimization of Multi level Relay Protection Adaptive
To improve the reliability and sensitivity of multi-level relay protection in distribution networks with distributed power sources, this study designs an adaptive setting strategy optimization
Effect of Distribution Automation on Protective Relaying
Protective relay settings have to be designed for the circuits where reverse power or fault current flow is possible. The complexity can increase if voltage regulators and/or reclosers are on the system but
