Semi- Automatic Transfer Scheme The 4.16kV main breakers SWG-0103 and SWG-0203 are presently set to trip on a long or short time overcurrent (51) and to trip and lock out on an instantaneous current. The main breakers will also trip on a bus fault (B90) or a fault on the associated 27.6kV breaker SWG-0101 or SWG-0201 ahead of the transformer supplying the 4.16kV switchgear. Presently, the semi-automatic transfer scheme is initiated from the two R4 auxiliary relays of the GE 750 Multilin Relay (JRT-0103/JRT-0203) of SWG-0103 and SWG-0203. They are set to change state on overcurrent (50 and 51) of the incoming feeder. This will cause the tie breaker SWG-0002 to close only if one of the main breakers is open. It does not allow for a transfer if there is a bus fault and this should be maintained as transferring into a fault would be disastrous. The transferring into a faulted bus is prevented by the B90 relays (JRT-0001/A/B/C AND JRT- 0002/A/B/C) on the 4.16kV busesbus-0001 and BUS-0002. If either bus is faulted the tie breaker will trip and lock out. In addition, the synchrocheck component of the GE750 can prevent transfer onto a live bus where synchronism is not possible. For the Semi- Automatic Transfer scheme between BUS-0201 and BUS-0202, the transfer should be initiated based on undervoltage on the incoming line. This would entail changing the programming of the SWG-0103 and SWG-0203 GE 750 Multilin relay to trip and to have the auxiliary relay R4 close on undervoltage. Voltage to BUS-0201 and BUS-0202 can also be supplied from co-generators and from emergency generators. In order, for the tie breaker to be allowed to close on undervoltage (on the loss of a main incoming source), confirmation that the bus is not powered or will not be powered from an alternative source must be achieved. From discussions with GHD, the co-generator system will be configured to trip the co-generators if there is a trip on the main 27.6kV breaker, the transformer feeder 27.6kV breakers or the 4.16kV main breakers. Confirmation that the emergency generator is not powering the bus at the same time as the utility is confirmed by a key interlock scheme preventing the main breakers and the emergency generator breakers from being closed at the same time. Voltage to BUS-0201 and BUS-0202 can also be supplied from one utility source Manby or Horner and confirmation that the bus that will be providing power is not in an undervoltage condition as well is required. This can be achieved by the use of the synchrocheck condition on the JRT-0002 of the tie breaker SWG-0002 this wiring is already present. The two main breakers SWG-0103 and SWG-0203 and the tie breaker SWG-0002 of the 4.16kV switchgear are hard-wired interlocked such that only two of the three breakers can be closed at any one time. This provides the required safety of this transfer scheme. The addition of the breaker trip on undervoltage is required as there are switching operations and there may be faults that will not open the main 4.16kV breaker that is seeing an undervoltage. The breaker would have to be tripped to allow the close of the tie breaker. It should be noted that, with this change the transformer breakers on the 27.6kV switchgear SWG-0101 and SWG-0201 would have to be closed to provide voltage to the main 4.16kV switchgear SWG-0103 and SWG-0203, otherwise the trip coil on the breakers will remain energized. The main incoming breakers (SWG-0100 and SWG-0200) have overvoltage and undervoltage protection settings. These protection settings will assist in protecting the plant from a voltage issue from Toronto Hydro. The Co-Generation System should provide protection from undervoltage and overvoltage either through the Co-Generation Breakers or the generator controls.

The function of the undervoltage relays on SWG-0103 and SWG-0203 is to initiate the transfer to a live bus on loss of power to either BUS-0201 or BUS-0202. The following settings are recommended for the Line Undervoltage settings of JRT-0103 and JRT-0203 of the SWG-0103 and SWG-0203, respectively. This causes a trip and lockout of the breaker in undervoltage conditions. Line Undervoltage: Trip Line Undervoltage Relays:4 Line Undervoltage PickUp = 0.8 x VT Line Undervoltage Curve=Definite Time Time Delay= 10s Line Undervoltage Minimum Voltage = 0.1 x VT to be confirmed at Site For JRT-0002 of SWG-0002 (the tie breaker on the 4.16kV switchgear), the synchrocheck setting can be incorporated to block transfer to a bus when one bus is not dead or in synchronism with the other bus. Without the Co-generators, there will be no source that will allow for synchronism across the bus. The two Toronto Hydro sources from Manby and Horner cannot be synchronized. The synchrocheck settings are recommended for JRT-0002: Synchrocheck Function: Alarm Synchrocheck Relays: 4 Dead Source Permissive: DLxDB (Dead Line or Dead Bus) Dead Bus Max: = 0.10 xvt to be confirmed at site Dead Line Max: = 0.10 xvt to be confirmed at site Live Bus Min = 0.80 x VT Live Line Min = 0.80 x VT Maximum Voltage Difference = 416V Maximum Angle Difference = 0 degree Maximum Frequency Difference = 0Hz 80% Voltage level was selected for trip on the undervoltage on the main 4.16kV breakers so the breaker should trip and transfer on 80%. Manual transfers can still be made on the 4.16kV by opening one of the main breakers and closing the tie. It is only at the 4.16kV level that an electronic transfer scheme can be incorporated. At the 27.6kV level there is only an open and close pushbutton on the remote panel for the breakers. The breakers are kirk interlocked so any transfer would have to be made manually. The only changes required to implement this automatic transfer system are: The switch on the Mimic panel must be changed to a two position switch with Semi-Automatic Transfer System On and Off as the positions Programming on the two 4.16kV Main Breakers relays JRT-0103 and JRT-0203 on SWG-0103 and SWG-0203 must be programmed to trip on undervoltage through Auxiliary Relay 4. As noted above. This is already wired up. Programming on JRT-0002 must be configured to provide a synchrocheck on Auxiliary Relay 4 as noted above. This will be more of a function to determine that the bus being transferred into is dead then a synchrocheck. This is already wired up in this matter.
