Study Notes
Power System Modeling
- Complex Power Flow: Power systems involve complex AC currents and voltages.
- Balanced and Reactance Diagrams: Power systems are often analyzed using diagrams showcasing system components and their impedances (reactances). These diagrams show balanced scenarios where currents in each phase are equal.
- Per-Unit System: This normalization method simplifies calculations by expressing values as a fraction of a base value. It facilitates easier comparisons and analysis.
- Per-Unit Representation: Crucial for transformers, synchronous machines, and loads, this representation standardizes values within calculations.
- Transformers: Per-unit representation simplifies the modeling and analysis of transformer characteristics.
- Synchronous Machines: Similar to transformers, per-unit representation allows easier calculations for synchronous machine parameters.
- Loads: Power system loads are also represented using per-unit values, unifying analysis across different components.
- Graph Theory: Power system components can be represented as a graph, aiding in understanding interconnections.
- Primitive Network: A simplified representation of the power system's structure.
- Z and Y Matrices: Used to represent the impedance and admittance characteristics of the network.
- Incidence Matrices: A matrix showing how network branches connect the nodes.
- Y-bus and Z-bus Matrices: These matrices are fundamental for simplifying circuit analysis. They provide the system's admittance or impedance in a matrix format, making circuit analysis more manageable.
