WAMS and Lightning Protection Quiz

What is the primary purpose of PMUs in WAMS?

• Measure solar irradiance

• Provide time-synchronized phasor data

• Store historical grid data

• Control circuit breakers

Which component aggregates PMU data in WAMS?

• MOV

• PDC

• SPD

• TVS diode

GPS in PMUs ensures synchronization accuracy of:

• 1 millisecond

• 1 microsecond

• 1 second

• 1 minute

A key challenge in implementing WAMS is:

• Low data volume

• High implementation cost

• Lack of communication protocols

• Manual fault detection

Adaptive protection schemes in WAMS adjust settings based on:

• Weather forecasts

• Real-time grid conditions

• Fixed manufacturer presets

• Historical load patterns

Which is NOT a WAMS application?

• Blackout prevention

• Solar panel manufacturing

• System observability

• Adaptive relay coordination

WAMS improves grid stability by:

• Reducing renewable energy use

• Enabling faster fault response

• Limiting transmission line length

• Increasing fossil fuel reliance

The communication infrastructure in WAMS is compared to:

• A circuit breaker

• A neural network

• A lightning rod

• A surge arrester

Future WAMS trends include:

• Manual grid adjustments

• Machine learning for fault prediction

• Reduced PMU deployment

• Eliminating GPS synchronization

Which device is NOT part of WAMS?

• PMU

• PDC

• MOV

• Fiber-optic cables
