Electronic Modular Control Panel II+ Paralleling (EMCP II+P) Caterpillar

Parallel Setpoint Programming OP5-3

Usage:

C32 SXC

The Synchronization setpoints within the GSC+P define various parameters that allow precise frequency and phase matching.

The setpoints are programmed (set) in the GSC+P at the factory to the default values that are in the following chart. The setpoints may be changed to satisfy the requirements of the customer. Also the setpoints may be changed to satisfy the requirements of the application.

OP5-3 Setpoints - Paralleling Programming
Setpoint	Name	Description	Range Of Value	Factory Default
P301	Synchronization Enable	Enables or disables the synchronization function, and specifies the type of Load Share control being driven.	0 - disabled 1 - Woodward	0
P302	Breaker Coil Time Limit	The maximum amount of time the breaker coil can be energized without damaging the coil.	0.2 to 5.0 seconds in increments of 0.1 second	1.0 second
P303	Voltage Limit Enable	Enables or disables the generator/bus voltage checking during automatic synchronization	0 - disabled 1 - enabled	1
P304	Voltage Limit	The maximum acceptable difference between the bus voltage and the oncoming voltage, expressed as a percentage of bus voltage.	1% to 15 % in increments of 1%	1%
P305 ⁽¹⁾	Phase Tolerance Limit	The maximum phase angle magnitude allowed for breaker closure	1 to 25 degrees in increments of 1 degree	5 degrees
P306 ⁽¹⁾	Dwell Time	The time during which the phase angle between the generator and the bus during synchronization.	0.1 to 1.0 seconds in increments of 0.1 second	0.5 second
P307 ⁽¹⁾ ⁽²⁾	Speed Control Gain	Controls how fast the engine speed will change during synchronization.	0.0% to 100.0% in increments of 0.1%	50.0%
P308 ⁽¹⁾ ⁽²⁾	Speed Control Rate	Controls the rate of change of the phase angle differencebetween the generator and the bus during synchronization.	0.0% to 100.0% in increments of 0.1%	50.0%
P309 ⁽¹⁾ ⁽²⁾	Speed Control Damping	Controls the amount of overshoot and settling time of engine speed during synchronization.	0.0% to 100.0% in increments of 0.1%	0.0%
P310	Dead Bus Closure Enable	Enables or disables automatic closing to a dead bus.	1 - enabled ⁽³⁾ 0 - disabled	0
P311	Dead Bus Limit	The maximum acceptable voltage for the bus to be considered dead, as a percent of rated voltage.	5% to 50% in increments of 1%	20%
P312	Dead Bus On Time Delay	The amount of time the GSC+P waits before closing to a dead bus.	0 to 120 seconds in increments of 1 second	0 seconds
P313	Frequency Match Notification Time	The amount of time before notification of possible synchronization failure. Must not be greater than the Maximum Synchronization Time.	5 to 1000 seconds in increments of 1 seconds	20 seconds
P314	Maximum Synchronization Time	The maximum amount of time to spend attempting to synchronize before setting the Synchronization Time-out Alarm	5 to 1000 seconds in increments of 1 second	30 seconds

^( 1 )	P305, P306, P307, P308, and P309 can be adjusted to precisely match individual engine response and breaker closure characteristics using OP11 - Synchronization Setpoint Tuning.
^( 2 )	The GSC+P uses P-I-D (proportional-integral-derivative) control to accomplish synchronization quickly and smoothly. The P parameter, I parameter, and D parameter are independantly controlled by setpoints P307, P308, and P309 respectively. Adjusting any one of these setpoints will not affect the other two settings. For more information, see Systems Operation, "Synchronization Mode" Setpoint Tuning.
^( 3 )	Dead bus closure will only work in the automatic mode, NOT in permissive mode or semi automatic mode.
