More and more loads are non-linear, introducing reactive power into the power grid and thus significantly impairing the power quality. NK 690v static var generator is an ideal product effectively compensate the reactive power.
Non-linear loads, by contrast with linear loads, have become increasingly common: frequency converters in drive systems, the large numbers of switch-mode power supplies used in IT and communications equipment, and also more and more in household electronics. Even lighting technology employs mainly non-linear power supplies. Non-linear loads becomes more and more in industrial plants, office buildings, data centers or even private households.
690v statcom static var generator based on our company many years experience, is a very reliable product. The user can set the parameters so that dynamically compensate reactive power, compensate for three phase unbalance, and compensate for voltage drop, etc.
690v static var generator statcom is a new type of electronic device for dynamic compensate reactive power . It can conduct real-time compensation to dynamic reactive power, and is used to overcome disadvantages of reactive compensation methods of traditional filters,thus realizing systematic reactive power compensation function. In addition, it is widely applied into power,metallurgy. petroleum, port, chemical and industrial and mining enterprises.
1. Modular design, any module failure will not affect the normal operation of other modules, greatly improving the reliability of the whole equipment; can achieve smooth expansion of multiple direct parallel operation.The master-slave control mode is used when multiple units are expanded; when multiple modules are connected in parallel, all modules can share a set of current transformers.
2. The odd-order harmonic currents of 2 to 50 times or less can be filtered out at the same time, and the harmonics of the 13 types of filtering can be set as needed.When the load current distortion rate is >20%, not less than 85%; when the load current distortion rate is <20%, not less than 75%; reactive power compensation can make the power factor reach 1; the three-phase current unbalance can be corrected to complete balance;
3. Use the fifth generation IGBT of imported international well-known brand, it can automatically adjust the output according to the harmonic current of the load, and dynamically filter;
4. Use the American Xilinx military-grade FPGA control chip, which has fast running speed and high reliability;
5. With a layered design, dust and rain will not adhere to the circuit board, adapting to the use under harsh conditions;
6. Filtering, compensating reactive power, compensating for three-phase unbalance can be single-selected or multi-selected, and can set the priority of functions;
7. Use the iterative DFT detection algorithm of sliding window , the calculation speed is fast, the transient response time is less than 0.1ms, and the full response time of device compensation is less than 20ms;
8. The output filtering uses the LCL structure to connect to the grid, and its own high-frequency carrier does not feed back to the grid, and there is no interference to other devices in the power distribution system;
9. Complete protection functions, including over-voltage, over-current, over-heat, short-circuit and other complete protection functions, as well as system self-diagnosis function;
10. It has a soft start control loop to avoid excessive inrush current at the moment of starting, and limits the current between the rated ranges;
11. Use the reliable current limiting control link. When the current to be compensated in the system is greater than the rated capacity of the device, the device can automatically limit the output to 100% capacity, maintain normal operation, and no faults such as overload burning;
12. The main circuit uses a three-level topology, and the output waveform has high quality and low switching loss;
13. The wall mounted module comes with a 4.3 touch screen for parameter setting, parameter viewing, status viewing, event viewing and more.It can also be centrally monitored by high-definition 7-inch touch screen, which is easy to operate. The screen displays the system and device operating parameters in real time, and has a fault alarm function.
14. Save space for users, the maximum power of 600mm wide cabinet is 300A/200kvar, and the power of 800mm wide cabinet can reach 750A/500kvar.
