When working in InfoSurge pro, you can simulate pump and turbine operation changes to predict and prevent potential surge events.
00:13
Changes in operating speed for pumps and turbines, changes in wicket gate openings for turbines,
00:20
and unexpected trips resulting from power loss, can all produce hydraulic transients in a pipe system.
00:28
Shock pressure occurs when pumping operation begins suddenly, as during a startup, and fluid is supplied to a static water column.
00:38
When a pump goes through a planned shutdown or power outage, it causes water column separation.
00:45
When the water column returns, shock pressure occurs.
00:49
Cavitation is possible following pump trips, as the flow reversal of the water column
00:56
causes the collapse of any vapor cavities that may have formed.
01:00
A time dependent change in speed ratios (operating speed/rated speed) may be defined for all types of pumps.
01:09
Pumps can also be tripped and the resulting rundown calculated based on the pump and motor inertia
01:16
and dynamic characteristics described in the pump file.
01:20
A trip can be specified with a ratchet, which prevents reverse rotation.
01:26
Pump trip and rachet changes require a pump file, which is selected in the pump surge data.
01:33
There are three types of pump operation changes that can be simulated in InfoSurge:
01:40
Pump speed:
01:42
The curve designated in the speed curve dictates the speed of the pump during the surge analysis.
01:48
Pump trip:
01:50
At the trip start time, the pump runs down according to the data specified in the pump surge data.
01:57
Once the pump has lost power, it may continue to turn, or turbine, or it may be forced to run backwards, or reverse turbine.
02:08
Pump ratchet:
02:10
A pump trip where there is a one-way bearing installed in the pump,
02:14
allowing it to turbine but not spin backwards.
02:18
The trip start time is the time at which the pump trip is initiated.
02:23
A time dependent change in the speed ratio or the wicket gate opening may be defined for turbines.
02:31
Turbines can also be tripped, and the resulting rundown is calculated
02:36
based on the turbine inertia and dynamic characteristics described in the Suter format.
02:43
Three types of turbine and wicket gate operation changes can be simulated in InfoSurge:
02:51
Turbine speed:
02:53
The curve designated in the speed curve dictates the turbine speed during the surge analysis.
03:00
Wicket gate setting:
03:02
The curve designated in the wicket gate setting curve dictates the wicket gate opening during the surge analysis.
03:11
Turbine trip:
03:13
At the trip start time, the turbine runs down according to the data specified in the pump/turbine surge data.
