Indeed. Normally the 60Hz runs low during the day and makes it up at night. The frequency drops due to large industrial loads during the day. I don't understand what the issue is with correcting the long-term average frequency at night is - it isn't like the plants are running un-monitored and they'd need to bring people in - they have to be monitored anyway. With the increasing use of large DC transmission lines to transmit billable power (as opposed to the between-region DC links which mainly serve as starting power for a blacked-out region), the inverter frequency doesn't need to be tied to spinning generators and won't drop as load increases (though since it has to be frequency-locked to the rest of the region's generation, it has to track frequency changes). As an example, the 3100MW Path 65 DC link. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
