We offer comprehensive grid study services that support the design, optimization, and safety of electrical grids. We perform load flow calculations, reactive power capacity calculations, fault current calculations, as well as load and sizing calculations for components to ensure the efficiency and reliability of the network. We also size overvoltage protection devices, conduct step voltage analysis, and calculate protection settings to keep the electrical network safe. Our services also include power and energy loss calculations, high-voltage cable sizing, as well as switching and transient studies. Additionally, we provide power quality and flicker studies to ensure optimal operating conditions for the network. We utilize industry-leading software such as PowerFactory, DSS, Cableizer, PSCAD, PSSE, and SafeGrid to ensure precise and reliable results in our analyses.
Load flow calculations verify the distribution of load and voltage levels across different parts of the power grid. Based on these calculations, network performance can be optimized, and it can be ensured that no part of the network exceeds allowable load limits.
Technical regulations require energy storage systems and power plants to generate and consume reactive power. Despro’s network analyses take these requirements into account and offer the most efficient solution for the customer. We can also evaluate whether the reactive power range specified in general connection conditions is met at the consumption site.
Short-circuit current calculations ensure that protective devices operate correctly and can provide adequate protection during faults. These calculations are an essential part of electrical network analysis, ensuring the safety, reliability, and efficiency of the network even in fault conditions.
Assessing the load and sizing of components ensures optimal performance, safety, and durability of the network. These calculations verify that all parts of the network can handle the required loads and fault conditions.
Surge protection safeguards network components and equipment from harmful voltage fluctuations. Properly sized protection ensures network safety, reliability, and durability during disturbances.
Despro has top experts for hazardous voltage analysis up to 400 kV, including grounding design. Tools used include DIgSILENT PowerFactory and SafeGrid.
These studies are a crucial part of network analysis, ensuring safety and reliability, especially during disturbances and faults.
Despro provides expert grounding design services for new installations and improvements to existing grids.
Design considers soil resistivity, fault currents, voltage levels, and environmental factors. Well-designed grounding enhances network performance, protects equipment, and ensures compliance with safety standards.
Properly configured protection devices effectively protect the network without causing unnecessary interruptions. We utilize DIgSILENT PowerFactory software to calculate protection settings.
Calculating losses helps optimize grid efficiency, enhance performance, and reduce costs.
Proper high-voltage cable sizing ensures safe and efficient power transmission across different parts of the grid and withstands all operating conditions, including fault scenarios.
Our experts use tools like DIgSILENT PowerFactory and Cableizer for cable dimensioning.
Switching and transient studies ensure network safety, reliability, and proper protection function. These analyses support optimal equipment selection, extended service life, and reduced costs.
Power quality assessments evaluate voltage quality, harmonic distortions, and electromagnetic interference, while flicker analysis focuses on voltage fluctuations. These studies help optimize network operation, improve power distribution quality, and reduce equipment failure risk.
Connection studies ensure that new connections do not compromise the reliability, safety, or efficiency of the grid. They evaluate the impact of the new load or generation on the network, technical requirements, network capacity, and any required investments.
Connection analysis prevents overloads, voltage disturbances, and other operational issues, while ensuring compliance with regulations and standards.
