Client: Covanta Energy
POWER Engineers executed its first communications scheme under the emerging international standard known as IEC 61850 as part of a $302 million expansion of a waste-to-energy plant in Kapolei, Hawaii. The plant is owned by the city and county of Honolulu.
Covanta Energy hired POWER to design the electrical control system for a new boiler at the plant, known locally as the Honolulu Program of Waste Energy Recovery (or H-POWER). The new electrical control system incorporated a GOOSE messaging scheme, which is one of the key features of IEC 61850.
IEC 61850 is a substation automation standard approved by the International Electrotechnical Commission to standardize substation Ethernet networks, to promote interoperability of equipment using object-oriented data models and to provide more information for a better control system. The idea is to provide more information at lower cost than present-day designs.
POWER performed electrical control system design, testing and commissioning for the boiler addition and designed and supervised construction of control panels required for the ECS system. POWER configured communication settings for approximately 35 IEDs, including protective relays and multi-function meters. POWER configured redundant Citect HMI servers used for monitoring and control of the ECS. The HMI is additionally used for trending and recording of historical data.
Working under a fast-track schedule, POWER designed, built, tested, and delivered four ECS control panels to the facility within four months. POWER also assisted Covanta with the development of SCADA design standards to be used in this project as well as in future installations.
