Installation 3.3 INTERCONNECTION WITH THE GENERATOR CONTROLLER The DSEP100 is intended to be placed into the application wiring in such a way as to decouple the mains and generator supplies in case of a mains failure when in parallel. Depending upon the requirements of the system, the relay is used to open the mains breaker, generator breaker or both as described below. -

Indicates that one of more of the phases are outside the settings of the Under Frequency / Over Frequency Alarms. 5.3 UNDER VOLTAGE / OVER VOLTAGE NOTE: DSEP100 modules before V1.5 have two stage alarms only. These modules are able to be updated using the DSE Configuration Suite PC Software. These are ‘5 stage’ alarms. -
Page 26: Over Average Voltage
Alarms 5.4 OVER AVERAGE VOLTAGE Indicates that the average of the monitored voltage phases, is outside the settings of the Over Average Voltage Alarm. The Average is calculated using voltage measurements taken over the proceeding ten seconds (10s rolling average). 5.5 LOSS OF MAINS (R.O.C.O.F. -
Page 27: What Methods Are Used For Loss Of Mains (Lom) Detection
Alarms 5.5.4 WHAT METHODS ARE USED FOR LOSS OF MAINS (LOM) DETECTION? LOM consists or a set of under and over voltage and frequency alarms supplemented with either Rate of Change of Frequency (ROCOF) or Vector Shift (VS) (also known as Vector Surge). Typically only ROCOF and VS are referred to as LOM, yet the voltage and frequency alarms alone are often quite effective in detecting island formation because the embedded generators are unable to maintain stable voltage and frequency so quickly drift to one of the alarm thresholds. -
Page 28: Example Of Potential To Not Detect A Mains Failure
Alarms 5.5.6.3 EXAMPLE OF POTENTIAL TO NOT DETECT A MAINS FAILURE In the below example, the local generator is providing a fixed power. When the load is low, this results in power being exported to the grid. When the load is high, the generator supplies some power, the mains provides the rest. -
Page 29: Example Of Rocof (Frequency Dip Upon Mains Failure)
Alarms 5.5.7 R.O.C.O.F. Indicates that the Rate of Change of Frequency (R.O.C.O.F.) is greater than the configured settings of the R.O.C.O.F. alarm for more than the configured time. R.O.C.O.F. detection of ‘mains failure when in parallel’ relies upon the relative steady state of the utility power grid frequency. -
Page 30: Example Of Rocof (Frequency Rise Upon A Mains Failure)
Alarms 5.5.7.2 EXAMPLE OF ROCOF (FREQUENCY RISE UPON A MAINS FAILURE) In this example, the generator is in parallel with the mains supply, in fixed export supplying all the requirements of the load and exporting the remaining power to the mains supply. Upon the mains failure event, the frequency of the generator increases due to load being removed. -
Page 31: Vector Shift
Alarms 5.5.8 VECTOR SHIFT Indicates that a Vector Shift in one or more of the monitored phases of the waveform has been measured greater than the configured settings of the Vector Shift alarm. Vector Shift detection of ‘mains failure when in parallel’ relies upon the relative steady state of the utility power grid. -
