Description

GE General Electric Technical Specifications: IS200IGDMH1BCB

Generation IS200IGDMH1BCB of power will be displayed on the IS200IGDMH1BCB as positive watts. By convention, an induction generator normally requires

reactive power from the system for excitation. This is displayed on the IS200IGDMH1BCB as negative vars. A synchronous generator on

the other hand has its own source of excitation and can be operated with either lagging or leading power factor. This is dis

played on the 489 as positive vars and negative vars, respectively. All power quantities are measured from the phase

phase voltage and the currents measured at the output CTs.

In a motor/generator application, it may be desirable not to trip or alarm on reactive power until the machine is online and

the IS200IGDMH1BCB field has been applied. Therefore, this feature can be blocked until the machine is online and adequate time has expired

during which the field had been applied. From that point forward, the reactive power trip and alarm elements will be active.

A value of zero for the block time indicates that the reactive power protection is active as soon as both current and voltage

are measured regardless of whether the generator is online or offline. Once the 3-phase total reactive power exceeds the

positive or negative level, for the specified delay, a trip or alarm will occur indicating a positive or negative Mvar condition.

The level is programmed in per unit of generator rated Mvar calculated from the rated MVA and rated power factor. The

reactive power elements can be used to detect loss of excitation. If the VT type is selected as “None” or VT fuse loss is

detected, the reactive power protection is disabled. Rated Mvars for the system can be calculated as follows:

For example, given Rated MVA = 100 MVA and Rated Power Factor = 0.85, we have

If enabled, once the magnitude of 3-phase total power exceeds the Pickup Level in the reverse direction (negative MW) for

a period of time specified by the Delay, a trip or alarm will occur. The level is programmed in per unit of generator rated MW

calculated from the rated MVA and rated power factor. If the generator is accelerated from the power system rather than the

prime mover, the reverse power element may be blocked from start for a specified period of time. A value of zero for the

block time indicates that the reverse power protection is active as soon as both current and voltage are measured regard

less of whether the generator is online or offline. If the VT type is selected as “None” or VT fuse loss is detected, the

reverse power protection is disabled.
