LOAD SHARING UNIT / LSU 113 DG DEIF

APPLICATIONS :
The LSU - 113 DG is a control unit for control of prime mover in a power unit.

The LSU - 113 DG can control a power unit
* In stand-alone mode, performing frequency control
* Parallel with grid , perfoming power control
* Parallel with other power units, performing frequency and power control
The unit is designed for connection to mechanical speed governor , however conjuction with the DEIF electronic potentiometer type EPN - 110DN or EPQ - 96 it can control electronic speed governors as well
The LSU - 113 DG has a built in frequency tranducer. if very stable frequency is wanted, an external frequency tranducer common for all the LSU - 113 DGs in power plant can be connected if a number of power units are to be synchronised to the busbar at the same time the frequency may likewise be controlled externally

GAC LOAD SHARING MODULE LSM 672

The function of the load sharing module isto proportionally share load beetween two or more generator sets while the system frequency is held constan.As an accessory to the electronic governing system.The LSM 672 measure the true power current, and truough a parallel cable interconection, continuously, controls the governor system. a neutral " N " is provided for connection to wye type generator sets.this reduces third order hamonic errors in power and load sharing controls.

AVR STAMFORD MX 341

The MX341 AVR is a two phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brush-less generator. Excitation power is derived from a three-phase permanent magnet generator ( PMG) , to isolate the AVR control circuits from the effects of nonlinear
loads and to reduce radio frequency interference on the generator terminals. MX341 AVR E000-2412 to suit Stamford Newage
