Allen-Bradley 1402-LS51 Line Synchronization Module

Allen-Bradley 1402-LS51 Line Synchronization Module

Description

The Line Synchronization Module, which fits into a standardAllen-Bradley 1771 10 chassis, provides an integratedpower-generation control solution. This module is designedto meet the needs of manufaclurers, system integrators, andsophisticated users of industrial and commercial alternatorsand cogeneration systems, or in applications that require two3-phase systems to be synchronized with each other. Thismodule provides a means for synchronization, load sharingand high-speed power system monitoring.

The design of this module reduces the complexity ofconventional technology, increases generator controlperformance, and provides an easily integrated automationplatform for both retrofit and new-power facilities.

The line synchronization module performs 3 functions:

The module measures appropriate parameters from thetwo three-phase systems and provides control and errorsignals to implement engine governor controlsynchronization.

The module provides an analog output that isrepresentative of the ratio of the power being supplied bythe altemnator to the output rating of the alternator, readsan analog input that represents the ratio of the totalsystem load being supplied to the total system capacity.and provides an error signal to adjust the altemator forproper load sharing based on the load requirements.

The module performs as a multi-function digital monitor forthe power system.

Data and control signals are communicated to the PLCprocessor via the 1771 backplane.
