Typical use cases

When engineering calculations are needed

Calculation studies are used for equipment selection, stability checks, contingency impact assessment, and preparation of engineering inputs for both design and operation of power systems.

Operating checks and design validation

Calculation studies help verify that selected network configurations and engineering decisions remain technically acceptable.

Risk and stability assessment

Engineering analysis helps identify the impact of contingencies, disturbances, and transient conditions before they occur in operation.

Support for project and operations decisions

Study results provide a basis for design development, modernization planning, and operation of electrical power systems.
