Provide both system detailed and equivalent models in fundamental frequency tools and electromagnetic transient tools. The system model includes 26 wind turbines connecting to a 230kV line service. Provide harmonic, TOV, NERC PRC 19-27, NERC MOD, studies; and arc flash model and analysis
Developed real-time offshore wind farm models (HVAC and HVDC at 816MW, 880MW, and 1.2GW) with WECC and IEEE-2800 standards. Analyzed the impacts of these farms (power, frequency, and power quality) when they are interconnected to bulk power grids, including protection system impacts, temporary overvoltages, subsynchronous resonances, ferroresonance, and primary frequency response. Advanced toolboxes used for offshore wind design and analysis include OpenWind, RTDS, Opal-RT, and PSCAD.
This project is located in ISO-NE territory. The 110MW project contains 40 solar inverters connected to a 115kV line. INS developed a PSCAD power system model and conducted the power factor study, harmonic study, transient overvoltages study, and NERC PRC-024 study.
A solar farm normally causes power fluctuation to the bulk power grid. This project developed a power plant control (PPC) system following Western Electricity Coordinating Council (WECC) compliance for the solar farm in combination with a microgrid at the power level of 40% of the solar farm, used PSCAD to ensure the system stability.
Review multiple solar & wind farm projects in the US and worldwide with the power levels of 50MW, 102MW, 225MW, 220MW, 227MW, 250MW.
– Supported to optimize the solar/wind farm layouts. Selected design and size for wind turbines and PV panels. Analyzed the farms’ annual energy production.
– Substation designs: Reviewed single-line and three-line diagrams for substations, relay, protection schemes, transformers, communication, and other electrical devices.
– Reviewed analysis of load flow, short circuits, grounding, harmonics, and other power quality issues.
