Consultancy on Regional Power System Master Plan for Required Reliability
of the Area/Customers and the Appropriate Capital Investment.
1. The Required Reliability Level
The required reliability level of regional supply network should be suitable
to the
characteristics of the area.
For instance, additional countermeasure should be taken in order to keep
higher
reliability of important area or customers at the point of social security.
2. Proposal of the Master Plan for Required Reliability
- Step1:
- Preparation of the appropriate Regional Power System Master Plan
- Step2:
- Evaluation of the Master Plan in comparison with a conventional style of
the client company's existing power system
3. Evaluation of the Appropriate Master Plan
As for reliability analysis, the expected outage MW by using N-1 planning
standard is estimated in some cases of power system plan. Besides the N-1 planning
standard method, the probability of outage by using Expected Outage Simulating
System is computed.
Our Experience:
Title: |
“High Dense Power-Transmission Planning in Taipower Northern Area
System” |
Client: |
Taiwan Power Company (Taipower) |
Term: |
April – August, 1998 |
Outline: |
Taipower has planned the“High Dense Power-Transmission Planning in
Taipower Northern Area System” for the purpose of planning the future
network system to meet the load demand and related power development program.
The system impact study was performed in advance to prevent negative influence
and overall study includes the analysis of power flow, bus duty, and stability
in Taipower system so as to meet Taipower system planning criteria. |
