Microgrid Short Circuit Analytics

With the need to analyze flowing faults within a microgrids peer-to-peer energy delivery model, a new generation of power system planning and analysis technology is required. Xendee's cutting-edge solutions are powered by the Electric Power Research Institute's simulation technologies and represent the output of over two decades of research and development in smart grid and microgrid analytics. Our cloud computing solutions provide design engineers with the unique ability to model microgrids and perform short circuit simulations on interconnected, meshed balanced and unbalanced multi-phase topologies.

Integrated ANSI C37 / IEEE and Classical calculation algorithms help engineers design microgrids and complex industrial systems that operate safely and reliably under various operating conditions. Depending on the desired calculation method, Peak, Momentary 1/2 cycle, 1st cycle, 1 1/2 - 4 cycle, interrupting, 8 cycle and 30 cycle faults at any 3-phase, 2-phase or 1-phase location within the power distribution system can be analyzed with granular reporting on current flows (at both terminals of all equipment), powers, angles and voltage. The flexibility to simulate virtually any fault scenario offers the extensibility needed to best analyze current and future microgrid designs.

Overview: Microgrid Short Circuit Analysis

Analyze and Study Flowing Faults

Xendee's microgrid short circuit analysis simulation provides the sophisticated features engineers need to model peer-to-peer multi-phase power distribution systems and traditional balanced 3-phase industrial networks. Novel algorithms deliver both world-class speed and accuracy.

Positive and zero sequence resistances, reactances and impedances are continuously calculated throughout the fault time cycles at every point in a system via sophisticated dynamic simulation techniques.

Time cycle varying machine impedances and X/R ratios are applied in computing the decaying DC component of fault currents, while contributions from machines and DG sources are modeled as Thevenin equivalents for each cycle time under study.
