September 4, 2002—Tecogen Inc., a manufacturer of natural gas-fueled commercial cooling and heat-recovery systems, recently announced that its 60-kilowatt and 75-kilowatt systems will meet a new standard governing interconnections between non-utility-owned distributed generation and the distribution grid.
Distributed generation refers to small-scale power-generating technologies that are located at the end-user’s site and interconnect with a utility’s power distribution grid.
Known in its draft form as IEEE P1547/D07, the new standard should help ease some of the permitting difficulties that distributed generation manufacturers have faced in the past. In order for a distributed generation customer to set up its on-site system and connect to the grid, numerous interconnection and liability requirements must be satisfied.
Following are the applicable sections of compliance to P1547, as well as the inclusive compliance to other established standards:
- 4.1.2 Integration with Area Electric Power System Grounding
- 4.1.4 Distributed Resources on Distribution Secondary Grid and Spot Networks
- 4.1.5.1 Inadvertent Energization
- 4.1.5.2 Reconnection after Area EPS Outage
- 4.1.6 Monitoring
- 4.1.7 Isolation Device
- 4.2.1 Voltage Disturbances—Tested
- 4.2.2 Frequency Disturbances—Tested
- 4.2.3 Disconnection for Faults
- 4.2.5 Feeder Reclosing Coordination
- 4.3.2 Limitation of Voltage Flicker Induced by the DR—Tested to EN61000-3-3
- 4.3.3 Harmonics—Tested to EN-61000-3-2
- 4.3.4 Immunity Protection—Tested to IEEE C37-90.2-1995
- 4.3.5 Surge Capability—Tested to IEEE C37-90.1-1989 & ANSI 62.41
