NYPA Research Leads to Increased Power Line Transfer Capability
November 7, 2016 -- A study by the New York Power Authority has provided a basis for strengthening the state's power grid by enhancing the power flow capability of the existing Marcy South power circuits from Central New York to the Catskills.
Engineer Ben Shperling recently presented the results of this research at the CIGRE (International Council on Large Electric Systems) Biennial Session in Paris. The work, titled 'Reduction of the TRV for Terminal Circuit Breakers on Series Compensated Lines,' was selected as the best paper submitted to the High Voltage Equipment Study Committee.
The $120 million Marcy South Series Compensation Project, a joint venture with New York State Electric & Gas that was energized in June, enables more electricity from renewable sources to flow from upstate to meet energy demand in more-populated downstate regions without having to build new power lines. The project is expected to provide up to 440 megawatts of additional transmission capacity, enough to power more than 400,000 homes.
The Marcy South project is a cornerstone of Governor Andrew M. Cuomo's Reforming the Energy Vision strategy to build an energy system that is more efficient, resilient and affordable for all New Yorkers. A key goal of REV and New York State is ensuring 50 percent of all electricity used in the state come from renewable sources by 2030.
The installation of series capacitors on three transmission lines allowed the power flow to increase by about 400 MW. Engineers from ABB, the equipment manufacturer, worked with NYPA to test and build the capacitor banks - the first installed in New York State.
While some of the equipment has been incorporated into other projects, this precise combination of devices had not been used before on high-voltage networks. The use of this technology meant the existing power equipment on the transmission lines and sub-stations did not have to be replaced, leading to significant savings. The upgraded system also allows planners and operators to have more flexibility in dispatching power to areas where it is needed most.
