Cigre 2021

EMTP® Team thanks everyone who attended the Cigre Canada Conference and visited our booth. It was a pleasure to see everyone in person with the return to a physical conference. We hope it was a good opportunity to engage with your peers, discuss your challenges with our team and understand how EMTP® is the solution for accurate computation of power system transients.

WHAT'S NEW?

CIGRE Canada 2021

It was a real pleasure to present EMTP®, the most complete and technically advanced software for simulation and analysis of power systems. For those interested, we also demonstrated our new features of EMTP® version 4.2, which deliver many improvements on several aspects.

Ground Fault Overvoltage with Inverter-Based Distributed Energy Resources

View

A Ground Fault Overvoltage (GFO) can occur in situations where an ungrounded transmission line and associated ungrounded transmission equipment is energized from distribution connected Distributed Energy Resource (DER) during a transmission single-phase-to-ground (SLG) fault. The condition could result in 1.73 pu overvoltage on phase to ground connected equipment which will be sustained until the DER ceases to energize the substation distribution transformer.

Optimization of Control Parameters of Grid-Connected PV System in EMTP®

View

It is observed that the controller gain parameters of the PV model have a significant impact on the PV plant’s response during the fault recovery and the PV plant’s interaction with the rest of the system in general. Manual tuning of the PV park parameter considering multiple fault and contingency scenarios is a time-consuming task and might even be impossible.

Reactive Power Energy Management, Analysis of Reactive Power Consumption in Solar Power Plant

View

For any Power Plant, it is aimed to have maximum Energy Generation and yielding for the Power Output. Solar power plant comprises PV cells, framing array by connecting with each solar panel and then connected with step-up transformer (Inductive element) by cable network (capacitance formed). The energy generated by PV cells are being converted by Solar inverters (Power electronics) and operated at almost Unity Power Factor.

Screening Studies for Susceptibility to Sub Synchronous Control Interaction using EMTP®

View

Sub Synchronous Control Interaction (SSCI) is can occur between type 3 wind turbines and a series capacitor. SSCI events can result in severe overvoltages that can damage equipment on the transmission system. This presentation will provide a brief history of SSCI, its impacts on the power system, and how to perform screening studies for SSCI susceptibility using EMTP®

Dynamic Overvoltage Conditions Experienced at a PV Solar Power Plant

View

We present the results from an investigation of the cause of dynamic overvoltage conditions experienced at a solar power plant, that resulted from energizing the PV solar plant 34.5 kV collection system feeders using a back-up diesel generator. The diesel generator unit was installed at the solar plant for emergency back-up power to the project, in case of power outage from the connecting transmission utility system.
