A short circuit study is a fundamental power system analysis that involves creating a comprehensive model of the electrical power system. This study focuses on analysing the flow of currents during fault conditions. The model encompasses all sources of electrical power, including utility connections and generators, as well as components that affect fault current, such as transformers and cables. By developing a complete model, it becomes possible to calculate various types of fault currents at different locations within the system.
coordination study integrates the findings of a short-circuit analysis with the characteristics of protective devices like relays and fuses. It showcases how these devices react to fault currents and assesses their capability to differentiate between faults that require immediate interruption and those that can A be managed by smaller downstream devices.
The key objectives of power system protection include:
1. Operating with minimum fault current: Ensuring that protective devices can effectively operate even under low fault current conditions.
2. Interrupting maximum fault current: Having the capability to safely interrupt the highest possible fault currents to protect the system and equipment.
3. Preventing spurious outages: Implementing proper protection grading to avoid unnecessary power outages caused by inadequate coordination.
4. Coordinating with upstream and downstream devices: Ensuring seamless coordination and communication between protective devices located both upstream and downstream in the power system.
Transient stability analysis allows engineers to precisely simulate power system dynamics and transients resulting from system disturbances and other events. ETAP Transient Stability utilizes comprehensive and validated equipment and protection characteristics, control models, and user-friendly graphical user-defined modelling. With the help of advanced algorithms, it performs analysis for a wide range of power systems, from industrial to transmission.
This analysis proves valuable for renewable energy plants, manufacturing facilities, and oil & gas production, manufacturing units by addressing power system load flow, optimizing system operating conditions, and adjusting control variable settings while ensuring compliance with system constraints.
By achieving system optimization, it is possible to reduce installation and operating costs, enhance overall system performance, and improve reliability and security.
As electronic power components become increasingly integrated into both existing and new power system networks, the occurrence of issues, failures, and spurious trips related to harmonics is on the rise. Harmonic Analysis plays a crucial role in this context by simulating harmonic current and voltage sources, identifying harmonic-related problems, mitigating nuisance trips, designing and testing filters, and reporting violations of harmonic voltage and current distortion limits.

When it comes to power system studies, VB® Engineering stands out as a leading company with expertise in this field. Our team of Chartered Electrical Engineers utilizes advanced digital modelling software such as ETAP and Dig SILENT to create virtual replicas, known as digital twins, of both low voltage (LV) and high voltage (HV) electrical power networks. With these digital twins, we are able to simulate the behaviour and performance of the power systems, making it possible to analyse their current state and evaluate various scenarios in a safe and controlled virtual environment. By leveraging the power of digital twins, our engineers can effectively plan and make informed decisions. This includes identifying potential issues and assessing the performance of the power systems without having any impact on the actual physical infrastructure. The digital twin also allows us to predict future behaviour and performance, leading to improved reliability and efficiency of the power system.
