Generator and Bus Protection and Metering

Multifunction protection guards against overvoltage, undervoltage, excessive forward and reverse power,

underfrequency, and overfrequency. Overcurrent, phase imbalance, loss of mains, frequency rate-of

change, phase differential, and neutral differential protection are available as options. Each protection

function has an adjustable pickup and time delay setting. Sixteen inverse time curves, in addition to user

programmable curves, enable the DGC-2020HD to offer overcurrent protection in a variety of

applications. Each protective element can be assigned to protect the generator, bus 1. or bus 2 sensing

inputs with settings groups.

Metered generator and bus parameters include voltage, current, frequency, vector shift, real power

(watts), apparent power (VA), and power factor (PF).

Engine Protection and Metering

Engine protection features include oil pressure and coolant temperature monitoring, overcrank protection,

ECU-specific protection elements, and diagnostic reporting.

Metered engine parameters include oil pressure, coolant temperature, battery voltage, speed, fuel level,

engine load, coolant level (from ECU), ECU-specific parameters, and run-time statistics.

Load Sharing

The DGC-2020HD provides analog outputs to the power system in the form of analog bias signals to the

voltage regulator and speed governor. A pulse width modulated (PWM) speed bias output is also

available. When the generator breaker is closed and load sharing is enabled, the DGC-2020HD shares

the real power load proportionally with other generators in the system. Load sharing can be implemented

on the Analog Load Share Line or through Ethernet communications. Reactive power (kvar) sharing is

accomplished through Ethernet communications.

The DECS-200N is a very compact Negative Forcing Digital Excitation Control System.

This compact design accommodates 63 Vdc and 125 Vdc applications up to 20 Adc

continuously. The on-board six-thyristor controlled rectifier bridge offers the highest

system performance possible, making the DECS-200N ideal for providing exceptional

system response, which makes it suitable for applications requiring power system

stabilizers.
