Chittagong - BPDB

2.4.6 Start-up Capability
The Company shall provide the following tele-control facilities required at the
LDC:
Control of the 132 kV circuit switches and reset of trip relays.
Control of generator active MW and reactive MVAr.
Indications of 132 kV switches and trip relays activated.
Measurement of 132 kV circuit MW, MVAr, and voltage quantities.
Alarm facilities in the event of any 132 kV circuit tripping and
protection-operated and communication equipment failure.
The Facility shall include a black start capability. It is anticipated that normal
start-up power will be brought in through the main transformers. The Company
may propose other schemes.
3.0 DESIGN PHILOSOPHY AND PRINCIPLES
3.1 DESIGN REQUIREMENTS
The Facility shall be of proven design (as specified in Article 2.1), built to appropriate
internationally recognized standards, and complying with all the applicable statutory
codes and regulations.
Facility reliability, availability, and maintainability consistent with high efficiency, are of
paramount importance.
The Facility shall be designed and equipment should be sized to permit reliable base load
operation over the complete range of anticipated ambient conditions without limiting the
plant output.
Please see Article 2.1, Article 4.2 and Article 4.2.1 for a description of the minimum
plant configuration requirement.
3.2 PERFORMANCE REQUIREMENTS
3.2.1 Operating Regime
The Facility shall be capable of both base load and peaking operation. For tariff
evaluation purposes, overall average annual net capacity factors will be assumed
as follows (see Figure 3.1):
For Years 1 through 15, Plant Factor = 80%
Equation C-1
Annual Net Capacity Factor (Plant Factor)
=
Net Power Output (MWh) for the
Annual Average Dependable Capacity (MW)
year
× Hours Per Year
“Hours Per Year” in Equation C-1 means 8760 hours.
The Facility should be capable of automatic operation and control at loads
between 100% and 25% of Dependable Capacity.
