PROTECTIVE RELAY WITH SYNCHRONIZED PHASOR MEASUREMENT CAPABILITY FOR USE IN ELECTRIC POWER SYSTEMS
摘要
<p>The relay system (10) obtains voltage and current values from a power line and uses a first sampling element to sample the voltage and current values at selected intervals of time. The resulting sampled signals are used for power system-wide protection, control, monitoring and metering. The sampled signals are then resampled at a rate which is a selected multiple of the power system frequency. The results of the resampling are used by processing circuitry for protection functions including fault determinations.</p>
