startup Extensive recording capabilities (last 100 events, three fault reports) Oscillography (120 cycles) Compact to reduce space requirements Modular construction for easy maintenance Applications Any size AC generators driven by steam, gas and hydraulic turbine Protection and Control Stator differential 100% stator ground faults Current unbalance Monitoring and Metering Negative sequence current Third harmonic voltages User Interfaces 16 character LED display, 20 button keypad Two RS232 ports Protection, control, monitoring and recording functions for AC generators in a single compact package. GE Multilin Protection and Control The DGP is a Digital Generator Protection system for any size of AC generator driven by steam, gas or hydraulic turbine. A high degree of security is provided via extensive self-diagnostics and an optional redundant power supply. Protection features include: Current Unbalance The DGP protects the generator from heating caused by current unbalance, using a formula based on the negative sequence component of the stator current. A linear reset allows the machine to cool down, and an alarm function is operated by the negative sequence component. Stator Differential High-speed protection during internal phase-to-phase faults and three-phase faults is provided. This function can provide high-speed phase-to-ground protection provided the neutral of the machine is grounded or another machine operating in parallel is grounded. Anti-Motoring The DGP includes a one or twostep anti-motoring reverse power function with individual time delay adjustments. One step can be used for sequential tripping of the generator, in which the turbine is tripped first. This step is enabled when closing of turbine inlet valves is indicated by digital input. The trip sequence is then continued when its delay time elapses. The second step is intended to provide backup to the sequential trip. If the sequential trip is not enabled, the two devices can be used as two-step reverse power functions with independent timers. Ground Overcurrent This inverse overcurrent function can be used to detect stator ground faults in a high or low resistance grounded generator system. Time Overcurrent with Voltage Restraint Protection against prolonged generator contribution to a fault on the system is provided through a time-overcurrent function with voltage restraint, as part of the system backup protection. This function is controlled by a fault detector and a Voltage Transformer Fuse Failure (VTFF) condition. Stator Ground Two overlapping zones provide stator ground fault detection in a high impedance grounded
