High Speed 2 Line

Answer

The peak electric power demand for the operation of the planned number of trains per hour for HS2 phases 1, 2A and 2B is shown in the table below.

Feeder Station	Max 1 minute RMS (MVA)	Max 30 minute RMS (MVA)
Ickenham	149.1	131.8
Quainton	179.1	167.1
Burton Green	176.5	157.1
Maximum Phase 1.	504.7	456
Newlands (Phase 2A)	152.73	83.99
Hoo Green	170.85	94.71
PH2 B AFTS 1	119.49	63.3
PH2 B AFTS 2	137.83	69.92
PH2 B AFTS 3	127.26	60.72
PH2 B AFTS 4	122.27	54.99
Maximum demand on Phase 2B.	677.63	343.64

The figures above represent the calculated demand based on a timetable that represents the train service pattern post opening of Phase 2B. The calculation is based on peak service provision during the period 07:00 to 11:00 which is the most power demanding period, ensuring that the traction power system is sized appropriately.

Demand is presented as the total 1 minute and 30 minute values at the primary side of the grid supply transformers.

It should be noted that the total maximum demand for Phase 1, Phase 2a or Phase 2B does not necessarily equate to the sum of the maximum demand for each of the feeder stations in the ‘Phase’ as the maximum demand at each feeder station doesn’t occur at the same time.
