NGD-840computer manual synchronization device
The controller uses the DSP chip as the core, can realize the fast AC sampling, to ensure the synchronization device fast, smooth the generator voltage, frequency regulation to the allowable value, the frequency difference, pressure difference requirement, calculation of phase difference and the closing leading angle prediction, can quickly, accurately capture the synchronization point, realization automatic quasi synchronizing parallel operation of generator and power system is accurate, fast, reliable. Compared with similar devices, has simple hardware, high integration, high reliability, perfect performance etc.. Device also can be used to predict phase, to be electric, frequency synchronization object variable parameter adjustment, improve the precision and the network speed.
Product parameters
Device power supply: DC220V or DC110V or AC220V;
Input signal::100V ± 50V generator;
Power: 100V ± 50V, were taken from the same object by two electrical transformer of the same name, switch input signal level of Vp = 24V, which is
The inside;
The output signal: growth, reduction, lifting, synchronization and fault six (contact) signal, the output to the relay contact capacity exchange way
The resistance of 220V, 3A, 48V DC, 3A;
Allow the frequency difference, difference and phase difference of electrical parameters can be modified;
FM, adjusted for the pulse output, pulse width and the parameter sequence modification;
Lead time in 001ms to 999ms by modifying parameters.
Product features
Design the structure of the hardware system of double CPU. Advanced digital signal processor (DSP) and single chip computer parallel processing technology, make full use of their
Advantage, and ensure that the system has powerful data processing capability, flexible, extensible and configurable;
