SCADA Power Grid OOP Quiz

Test your understanding of Object-Oriented Programming principles applied to Supervisory Control and Data Acquisition systems for electrical power grids.

Abstraction

Hiding complex implementation details while exposing only essential features.

Encapsulation

Bundling data and methods together, restricting direct access to internal state.

Inheritance

Creating new classes based on existing ones to promote code reuse.

Polymorphism

Allowing objects of different types to be treated as objects of a common type.

1
In a SCADA system, you create a base class PowerComponent with method getStatus(), then derive Transformer and CircuitBreaker from it. This is an example of:
2
A GridSensor class exposes public methods getVoltage() and setCalibration() but keeps its internal ADC reading logic and calibration coefficients private. This demonstrates:
3
A SCADA monitoring function can call getStatus() on any object of type PowerComponent, and the system automatically executes the appropriate method for transformers, breakers, or relays. This is:
4
Designing a RemoteTerminalUnit interface that hides whether communication uses IEC 60870-5-104, DNP3, or Modbus protocols from the rest of the SCADA system illustrates:
5
Creating ProtectiveRelay as a base class with common functionality, then deriving DistanceRelay, DifferentialRelay, and OvercurrentRelay from it demonstrates:
6
A DataPoint class that stores measurement values and timestamps, and only allows access through validated setter methods with range checking, is primarily an example of:
7
Implementing different alarm notification strategies (SMS, Email, Pager) where the SCADA alarm manager can treat them all as NotificationHandler objects illustrates:
8
Creating a simplified IED (Intelligent Electronic Device) interface that hides the complexities of vendor-specific protocols like IEC 61850 or IEC 60870 primarily demonstrates:
9
In a SCADA historian module, creating DataStorage as a base class and then deriving SQLStorage, NoSQLStorage, and TimeSeriesStorage from it primarily demonstrates:
10
A SCADA system where you can add a new WindTurbineController class that works with existing grid control algorithms without modifying them, because it implements the standard PowerSource interface, demonstrates:
