POWER AUTOMATION SYSTEM…
In today’s power deficient industrial environment most industries choose to be self-reliant.
Captive power plants / DG sets are installed across all industries.
NEED OF THE HOUR….
The common unforeseen problems customers face.
• How to synchronize among the DG’s. How to ensure optimum load sharing between the DG’s. • How to protect the system from electrical / mechanical damage • How to schedule loads - critical /non-critical to avoid power breakdown.
KEY BENEFITS • Monitoring and control of all electrical parameters without any
transducers.
• User configurable for unparalleled flexibility in applications.
• Integrated ‘synchronizer’, load sharer manager & power
monitor.
• Inbuilt temperature scanners (bearing, winding etc).
• No need of conventional relays. All protection relays built in .
• Auxiliary drive control
• DG load management for fuel saving
• Unmanned plant operation with fault diagnosis
• Synchronization with grid to avoid heavy starting current of big
drives on alternator
• Power factor correction to enhance DG capacity
FEATURES OF PLC SYSTEM • The system will directly accept CT & PT signals for Electrical
parameter monitoring and control Depending upon the load
requirement starting and stopping of DG sets.
• Automatic synchronizing of DG sets in Auto mode.
• Active and Reactive power sharing of each DG set.
• Automatic selection of next DG as master after stopping
/tripping of master DG to close NGR circuit breaker.
• Monitoring of electrical parameter per DG, Voltage , Frequency,
Reactive load, active load, Energy produced , voltage error (%),
Frequency error and phase angle error etc.
• Load shedding system (Fast acting, Under frequency, Gradual overload )
• Grid maximum demand controller
• Provision to test the DG after repairs through PLC
• Isochronous/ Droop mode Synchronization.
FEATURES OF PLC SYSTEM Cont… • Status and Control of outgoing breakers.
• Back up protection electrical / mechanical by time delayed tripping of
DG sets.
• Reverse power, Reverse KVAR , under voltage , Over voltage, Under/ over frequency, over current, low lube oil pressure, high cooling water pump, over speed etc.
• Isochronous/ Droop mode Synchronization.
• Incorporated Data acquisition system for recording & display of all important & critical parameters of the engine, alternator & system as such in total operation of the system will also be through operator interface with graphics (SCADA) screen.
• “B” checks alarm after each DG complete 300 hours of running for proper maintenance.
• Tripping of less priority loads in the plant in case of under frequency of bus both in isolation as well as synchronized mode.
PLC SYSTEM OVERVIEW • Automatically synchronizes a cogeneration or stand-by power
system
• Regulates power output to maximize the utilization of available generated power
• High performance, cost effective solution for the retrofit of existing / new power generation control equipment
• Increases system speed, accuracy & overall performance while reducing the integration time, cost, space & hardware
