Electrical System Modeling

ElecBuilder™

ElecBuilder is a high-fidelity solution for real-time modeling and simulation of electrical systems in power plants and industrial facilities. From normal operating conditions to abnormal states and accident scenarios, it accurately analyzes voltage, current, and overall power flow based on physical principles.

ElecBuilder™

ElecBuilder™ structurally visualizes AC/DC electrical systems and generator–load–distribution architectures in power plants and industrial facilities, implementing them as high-precision analytical models that reflect real-time behavior. It supports complex operating conditions—including voltage and current responses of electrical loads, multi-bus configurations, protective relays, and insulation breakdown—and, when integrated with the MPSP executor (MPSPexec), simulates system responses to operating scenarios in real time.

Message Connected to Brand Philosophy

ElecBuilder is a tool that handles complexity with precision while expressing it intuitively.
Rather than simplifying complex electrical networks, it analyzes them structurally and presents them clearly through visualization, enabling anyone to design without errors.
Designing systems where stability is ensured by the structure itself—not by human perfection—is the essence of ElecBuilder.
