Underground cable maintenance and management in power sector

The Second Phase
Second Phase of the Solution envisaged consists of Standard Maintenance Modules and Network Analysis.

The Module would ensure the benefits as below:

• Maintenance
  
  Management ensures use of scientific and centralized inventory management.
• Operations Management and Scheduling
• Crew and Spares control
• Call Center or Trouble Ticket Management

Network Analysis of the Distribution System would also be covered under the module ensuring the following:

Load Model
With the Near Physical environment provided by the system, true load points can be used. Network Simulation and Analysis can thus be performed.

Network Tracing
Load flow programs would help in ‘tracing’ Load in all lines and components of the network. Data Redundancy would be reduced [8]

Fault Isolation and Restoration
Fault isolation and Restoration in the Network could be done directly done on the system using modules provided for the same.

The Third Phase
The Solution would have to be finally integrated to a Online data acquisition system (SCADA) and would thus enable online query and analysis on real-time system.

Also Expert System based module would be provided for improved administration and management of the system.

These modules would work on top of the previous two modules. Such a System is expected to provide Knowledge based allocation and Scheduling along with Decision Support System[9].

Problems on the Way
The Solution aimed at though comprehensive and unique, as discussed earlier has to be implemented in phases and the success of the system as a whole would depend very much on the successful completion of each of the phases. Though the architecture of the same is modular success of the initial phases would determine the effectiveness of the system to a large extent. This is very much in consistence with waterfall cycle of Software Engineering [10].

However there are some External and not so easily controllable factors that are critical to the success of the system which are discussed as follows.

Data Related
Both the Geographic and Non-Geographic data is to be entered and kept updated by the users. The system being as accurate as the databases it works on, it follows naturally that the database should be secure, actively updated and easily accessible.
