Does G83 enable the manufacture and continuous use of an SSEG rated at 16A per phase in parallel with the mains, operating within the nominal voltage range as defined by ESQCR. 230Vac +10% -6%? A continuous power output of 3286W to 4048W depending on supply terminal voltage and generator power factor.
Or does G83 not only limit the current to 16A per phase but also limit the continuous output power to 3680W?
G83 has a Purpose. It provides sufficient information to allow:
[a. SSEG Manufacturers to design and market a product that is suitable for connection to the public low-voltage distribution Network;
b. Users, Manufacturers and Installers of SSEG Units to be aware of the requirements that will be made by the local Distribution Network Operator (DNO) before the SSEG installation will be accepted for connection to the DNO’s Network;
c. DNOs to confirm that the SSEG installation is compliant with the relevant
international, national and industry standards.]
Depending upon which of the above categories you belong will likely give bias to your interpretation of the ER.
No power limit figure is mentioned in G83. However it is possible to derive a figure of 3680W from information given in Scope and Definitions.
[For the purposes of this Engineering Recommendation a SSEG is a source of electrical energy rated up to and including 16 Ampere per phase, single or multiphase, 230/400 Volts ac.]
It is necessary to have maximum 100% power output figure assigned to a SSEG to enable tests specified in the annexes to be undertaken and recorded on the type verification test sheet.
Clause 5.6 Power Factor is part of Requirements, and has to be met.
[When operating at rated power the SSEG shall operate at a power factor within the range 0.95 lagging to 0.95 leading relative to the voltage waveform unless otherwise agreed with the DNO.]
Again it is necessary to assign the SSEG with a power output figure. If 230V 16A is used as stated in Scope and definitions, then the continuous true power output would range from 3286W to a maximum 3680W depending on supply terminal voltage and generator power factor.
The Interface protection clause 5.3.1 states that the SSEG [shall be designed to withstand without adverse effect, voltage variations within the limits of Over Voltage 264 volts (230 +14.7%) Under Voltage 207 volts (230 –10%) or within the setting values on the interface protection if they are lower. As a minimum the SSEG should operate satisfactorily within the full tolerance range of the Nominal Voltage and Frequency.]
This still leaves the problem of clause 5.6 and how rated power is defined?
What you mean by "Under this load the voltage is 242 V"? Surely the voltage is whatever it is.
Sorry. I should have phrased that better and said, for this load condition to occur the grid voltage at the generator terminals would need to be 242V.
Everyone knows that to deviate from the grid voltage will result in cheeky and troublesome gesticulating electric monkeys.
