Hope Sunland SB70P series low-voltage shore power supply 50Hz±5%

Introduction: SB70P series four-quadrant variable frequency power supply, using IGBT rectification; The input of the variable frequency power supply has an LC filter to ensure that the input harmonics are <4%, and at the same time, it can ensure that the variable frequency power supply itself will not be interfered by the harmonics of the dock power grid, and ensure the safety of the variable frequency power supply; The output of the shore power conversion frequency power supply system adopts high carrier frequency and output LC filtering to ensure that the total harmonic of the output voltage is within 3% and the single harmonic is within 2%, so as to ensure the normal power consumption of the shipborne equipment.

peculiarity

The input adopts AFE active rectification design, the power factor is almost close to 1, and the low harmonic design reduces the harmonic pollution to the power grid;

The variable frequency power supply device controller adopts the mode of DSP+ARM+FPGA, adopts the configuration of multiple digital microprocessors, each chip adopts the most advanced configuration, the division of labor is clear, and each plays its own strengths, DSP main frequency 150M special motor control chip processing algorithm, ARM's rich external interface is convenient to realize various excuses and control functions, FPGA powerful data processing capabilities, and rich interfaces ensure the communication and fault feedback between the main controller and each unit; The processing speed of the main controller has reached the nanosecond level to ensure that there is no "crash" phenomenon;

Variable frequency power supply efficiency ≥ 97% (100% load);

Heavy-duty design, when the ship has a high-power load start, it can not be affected, 1.2 times overload for 60 minutes, 1.5 times overload for 1 minute, 2-4 times anti-time protection, protection curve can be set. In view of the reactive power interaction between the reverse power and the ship's transformer charging at the moment of grid connection, the hardware design and software design can effectively suppress various impact situations in the process of grid connection, so that the success rate of ship connection is 100%;

In the process of grid connection, the reverse power will be generated due to the inspection error of the marine synchronous grid connection system, which will lead to the generation of reverse power in the process of grid connection. The reverse power inhibition technology developed by our department in this case can automatically detect the inverse power and realize automatic adjustment, and suppress the generation of inverse power from the root through software control, completely solve the problem of inverse power, and lead the industry in system reliability. The insulation grade of the transformer is H grade, and the temperature upgrade is B grade assessment;

Degree of protection: IP30;

The rectifier inverter unit adopts modular design, which is easy to maintain and has high reliability;
