In TPS, there are two types of Paralleling Sets. One is Normal Type which controlled by many meters, the other is Auto-Start Type which controlled by PLC control panel. The Normal Type is used to be used in the foretime but the Auto-Start Type is high frequency used in now present.

Paralleling conditions:
·Generator sets should be equipped with electrical governor system
·Incoming generator phase sequence must be same as main power
·Voltage difference is in the limit between generator and main power
·Frequency difference is in the limit between generator and main power
·Phase angle difference is in the limit between generator and main power

Functions and protections:
·Reverse power
·Dead bus sensing
·Voltage matching
·Frequency matching
·Phase angle matching
·Ramp control
·Blend control
·Circuit breaker closing ontract
·Engine speed control

· Intuitive interface makes operation simple. Little or no learning curve required to operate system
· A main screen with navigation buttons and non-system critical button/switches
· System testing screen allowing the operator to manually initiate automatic system testing operations
· Generator interface settings latched into the PLC control system upon entry
· System load add/shed manual control redundant to hard-wired manual control switches in master control
· Generator optimization settings latched into PLC control system upon entry
· The system is designed to dynamically add or shed load based on the system load level rather than using inflexible load blocks
· The system is programmed to dynamically track the size of each load individually. This allows the system to quickly determine exactly how many loads are to be added to or shed from the system, whether it is in the middle of the afternoon or in the middle of the night.
· Capable of soft loading and unloading the generator
· Var/pf controller built in, load sharing (kW and kva)
· Equipped with its own automatic synchronizer that checks for voltage matching
