Substation Testing and

Commissioning Time Schedules
and Resources Management

23.1 INTRODUCTION
In order to complete the substation commissioning work in efficiently and
effectively we should manage the activities involved in these tests and man-
age resources to match each activity with the correct number of people with
the appropriate skills and also manage the time to do these activities wisely,
as increased time spent inevitably leads to increased costs.

23.2 PRACTICAL EXAMPLE OF EXECUTED SUBSTATIONS
23.2.1 Gas Insulated System Substation

The substation has the following data:
500/220 kV substation
3 bays—500 kV feeders 1 2 spare feeders
12 bays—220 kV feeders 1 2 spare feeders
3 bays—transformers 500/220 kV and 3 transformers 220/11 kV
20 feeders—11 kV feeders
Refer to the following schedule for activities, required manpower, and
required time to completion.
A 5 no. of feeder bays, B 5 no. of transformer bays, C 5 no. of 11 kV
feeders.
Note that some activities can be done in parallel (Table 23.1).
A 5 3 1 2 1 12 1 2 5 19
B 5 3 1 3 5 6
C 5 11 kV feeders 5 20
For a substation in this example (Table 23.2), where A, B, C, D, F, G, P,
N, K, and M are the 10 different engineers assigned to do this job.
Total required months 5 6 months
