At ALSA Engineering Projects, we specialize in conducting sophisticated electrical network studies to analyze, design, and optimize power systems. We leverage industry-leading software like DIgSILENT PowerFactory and Siemens PSS/E to provide highly accurate simulations and actionable insights. Our comprehensive suite of studies covers every aspect of system behavior, ensuring your electrical infrastructure operates reliably, safely, and efficiently.
Our Core Capabilities Include:
1. Steady-State Analysis:
- Load Flow Studies: We perform meticulous load flow analyses to determine precise voltage magnitudes and angles across all buses, as well as active and reactive power flows on lines and transformers. This analysis identifies overloaded components and voltage violations, facilitating optimal grid planning and loss reduction.
- Short Circuit Studies: We calculate prospective short-circuit currents for all fault types (three-phase, line-to-ground, etc.) at any point in the network, adhering to international standards (IEC, ANSI/IEEE). This study is crucial for specifying correct equipment ratings and ensuring infrastructure can withstand fault stresses safely.
2. Protection System Studies:
- Protection Coordination and Relay Setting: We design and coordinate protective relay settings to achieve optimal selectivity. By utilizing time-current characteristic (TCC) curves, we ensure only the faulted section of the network is isolated, maximizing service continuity while rapidly mitigating damage.
- Arc Flash Studies: We calculate incident energy levels and define arc flash boundaries across the system. This provides critical information for determining appropriate Personal Protective Equipment (PPE) requirements, enhancing personnel safety.
3. Static and Dynamic System Stability Studies:
- Voltage Stability Analysis: We evaluate the system’s ability to maintain acceptable voltage levels under severe loading or outage conditions, identifying the need for reactive power compensation and reinforcing critical grid points.
- Frequency Stability Analysis: We simulate system frequency response following generation losses or sudden load changes, ensuring robust performance and defining effective under-frequency load shedding (UFLS) schemes.
- Transient Stability Analysis: We model the system’s behavior immediately following major disturbances, such as faults or component switching. This analysis guarantees that generation units remain in synchronism and the overall grid returns to a stable operating state.
4. Power Quality and Advanced Analyses:
- Harmonic Analysis: We identify potential harmonic sources, calculate distortion levels, and design mitigation filters to ensure compliance with power quality standards (like IEEE 519), protecting sensitive equipment.
- Insulation Coordination: We perform switching and lightning surge analyses to optimize insulation levels and surge arrester placement, protecting infrastructure from overvoltages.
