Biomass Steam Generator Integration

This project involved the design, installation and integration of a 10 MVA/8.5 MW biomass steam powered generator into the medium voltage lumber mill power delivery system.

The existing mill created significant volumes of wood chips and sawdust from the milling of logs into dimensioned lumber. The existence of the wood waste created an opportunity for the mill to burn the residual wood waste and create steam to use in the drying kilns and power to drive a steam driven power generator thus saving energy by reducing purchases of electricity to run the mill and purchasing fossil fuel to operate the drying kilns.

The mill complex was located approximately 18 miles from the nearest 34.5 kV utility substation and service was transformed to 12.47 kV at the mill interconnection to establish an onsite 12.47 kV power delivery system.

In 2015, the client added a steam powered turbine generator to reduce energy cost, enhance electric system reliability, reduce and provide a market for waste wood for area loggers. RLC was hired to advise and assist with the planning, design and integration of the generator electrical and control systems. We conducted a site visit in order to create several as built control cabinet drawings. We also performed additional site investigations to resolve electrical issues in conjunction with the utility. Our engineers reviewed utility data and obtained power monitoring data to analyze and identify root causes for events that occurred. Our team guided the interconnection application and study process, served as owner’s electrical engineer, and facilitated the commissioning of the medium voltage switchgear and control systems. RLC directed the energization and initial synchronization of the system and created final record drawings for the generator installation.

COMPREHENSIVE PROTECTION ENGINEERING

Revere Station P168: Upgrade existing relays and protection to dual pilot schemes, utilizing DCB and POTT.

Wickford Junction (Dry Bridge): New 115/34.5 kV Substation with one 34.5kV breaker-and-a-half bay, and associated equipment. Two 115kV lines enter the station. Each 115kV line is connected to Bus 1 and Bus 2 through 115kV circuit breakers. Each bus is connected to a 115/34.5kV transformer via an air break switch. Transformers No. 1 and No. 2 are rated 33/44/55 MVA, are connected wye at 115kV and grounded-wye at 34.5kV, with a buried delta tertiary. The transformers are equipped with LTCs. The 34.5kV buses can be tied together via a normally opened breaker leaving Feeder 1 tied to Transformer 1 and Feeder 2 tied to Transformer 2. The design includes consideration to allow for the 34.5kV immediate dead bus transfer capabilities to be implemented in the future. The station has approximately 100MW of photovoltaic generation owned by others connected to the 34.5kV feeders.

West Kingston: New protection scheme for 115kV Line 190S; Install two (2) RFL9745 devices at West Kingston #62 to enable a direct transfer trip (DTT) protection scheme on the L-190S 115kV line.

Kent County: New protection scheme for 115kV Line 190N; Install two (2) RFL9745 devices at Kent County #22 to enable a direct transfer trip (DTT) protection scheme on the L-190N 115kV line.
