Engineering Power Solutions uses the most powerful, latest engineering software on the market providing stand-alone power system studies designed to answer seemingly simple questions:
How do I increase the reliability of my system?
Is the protection of my system properly co-ordinated?
How much further can I expand and optimise my current system without major investments?
This is the most basic power system study. It creates a model of the electrical power system and analyses currents under fault conditions. The model includes all sources of electrical power (such as utility connections and generators), as well as any component that reduces fault current (transformers and cables, for example). A complete model makes it possible to calculate different types of fault currents at each location in the system. Examples are:
Knowing the exact fault level and comparing it to equipment capabilities can locate problem areas, reduce costs when selecting new equipment and establish the limits for adding new generators. The study results and findings are presented in a report that includes input data of the constructed model and tables with calculated values.
A coordination study combines the results of a short-circuit analysis with the properties of protective devices such as relays and fuses. It demonstrates how individual devices respond to fault currents and reveals their ability to discriminate between faults that should be interrupted and those that should be handled by smaller devices downstream.
With a protection co-ordination and grading study, the following is evaluated for each protective device:
A co-ordination study ensures that protective devices will have optimal settings that properly protect the system against fault conditions. At the same time, it offers selectivity: a fault will only disrupt the part of the system where it is located, whereas the rest of the system will be able to continue functioning as normal. The study will result in a report that includes a short-circuit analysis, an overview of recommended settings and a graphical representation of device time-current characteristics.
Transient stability analysis enables engineers to accurately simulate power system dynamics and transients via system disturbances and other events. ETAP Transient Stability leverages detailed and validated equipment & protection characteristics, controls models and user-friendly graphical user defined modeling together with advanced algorithms to perform analysis for industrial to transmission power systems.
EPS has completed many transient stability studies including:
This analysis is useful for renewable energy plants, manufacturing and oil&gas production to solve power system load flow, optimise system operating conditions, and adjusts control variable settings, while ensuring system constraints are not violated.
An optimized system will reduce the installation and/or operating cost, improve overall system performance, and increase its reliability and security. The program also provides a variety of other choices of optimization objectives, which covers virtually all the optimization criteria for a real power system:
With an increase of electronic power components being integrated into existing and new power system networks we are finding more and more issues, failures and spurious trips synonymous with harmonics. With the Harmonic Analysis we can simulate harmonic current and voltage sources, identify harmonic problems, reduce nuisance trips, design and test filters, and report harmonic voltage and current distortion limit violations.
We provide all grid and distribution code compliance studies for any international requirement (including ENTSO-E requirements) for synchronous or non-synchronous plant. We have completed over 100 grid connection design & studies and therefore understand the results that the utility companies are looking for. If non-compliance becomes apparent, then we can propose design modifications or recommend a course of action to resolve the issue, including supporting discussions with the utility / system operator. Examples of the studies we provide for planning, design and grid connection of conventional and renewable plants (such as PV plants or wind farms) include:
Design, management and independent due diligence for grid connections include:
