LOAD DEMAND START STOP SYSTEM
P o w e r G r i d M o d e r n i z a t i o n f ro m L - 3 We s t w o o d
The Load Demand Start Stop (LDSS) System is L-3 Westwood’s next-generation approach to power grid modernization and was designed to work in conjunction with 30kW and 60kW, B Model, Tactical Quiet Generator (TQG) sets. The LDSS System can be utilized with as few as two TQG’s or up to a total of six TQG’s (30kW, 60kW, or a combination of sizes) and can be adapted to work with other types of generator sets.
LDSS SYSTEM BENEFITS
LDSS SYSTEM FEATURES
• Provides for connection of generator sets into a ring-bus, micro-grid power system configuration
• Demand initiated startup
• Power grid management system automatically starts and stops generator sets based upon load requirements • Reduces fuel consumption by up to 50% over traditional generator set operating methodology depending upon load profile • Reduces maintenance cost due to efficient utilization of generator sets
• Dry contact initiated start (manual starting from remote location) • Dry contact control of the auxiliary fuel system (manual enabling/disabling from a remote location) • Sequence and stagger generator use in a variety of methods, including by service time, generator set size, and individual unit ID • Demand initiated shutdown • Dry contact shutdown (manual shutdown from a remote location) • Automatic frequency and voltage matching during synchronization • Communication between controllers via PLC (Power Line Communication) or by hardwired Ethernet • Optional MODBUS control and monitoring from a remote location
