Description

 

The JSW-1 Switchboard Simulator is a training system that will allow a trainee to perform various drills on a switchboard with

 

• The look and feel of a real ship's switchboard, and
• Electrical faults and conditions that will be encountered onboard a typical Navy Ship.

 

The system consists of a High Power Switchboard, Load Centres, Loads, Shore Supply Cope Point, Shore Connection Box and a Condition Simulator.

A reporting system is provided to generate a hard copy evidence of the trainee's operation of the switchboard and the procedures used to clear faults and conditions.

 

Features

 

Switchboard

 

The Switchboard is of metal construction, 'dead front' design and painted standard Navy Light Grey. Power flow details are shown permanently on the front of the switchboard panels. The Switchboard consists of six sections:

 

• Control and Monitoring for Alternator Number One
• Synchronising Section and Earth Detection Section
• Control and Monitoring for Alternator Number Two
• Shore Power Control and Monitoring
• Load Centre No. 1
• Load Centre No. 2

 

 

Load Centres

Two Load Centres are fitted - one on either side of the switchboard. Each panel has ten circuit breakers that connect to loads of different power ratings. The breakers are provided with identifying tags. The loads can be remotely connected or disconnected from the condition simulator. Loads and their respective tags can be easily changed. 

 

Condition Simulator

A Condition Simulator (CSI) is provided for the control. Sited remotely from the switchboard, the CSI allows the Instructor to present the following conditions instantly, over a variable time scale or randomly, as applicable:

 

• Tripping of Alternator No 1 and/or No 2 Supply Breaker, Bus Bar Linking Switch and the Shore Supply Breaker
• 450 Volt Earth on any of three phases on either load centre, accompanied by visual alarm
• Remote tripping of load circuit breakers, switching on/off loads on each circuit
• Immediate or gradual shut down of the prime movers driving the alternators
• Activation of any of six non critical monitoring alarms
• Tripping of Shore Supply Breaker at shore supply source
• Failure of the Synchroscope
• Failure of the phase sequence lamps in the shore supply connection box
• Loss of prime mover control
• Loss of excitation to the alternators
• AVR failure
• Start/Stop facilities for the three power supplies
• Automatic operation of the switchboard and plant
• Printout of trainee actions with switchboard controls following activation of conditions or when synchronising.
