Product Description

The modular power conditioner is connected in parallel in the power grid system, and the load current in the power grid is detected in real time through an external CT, and the DSP/FPGA/CPLD chip is used to cooperate with the latest fast harmonic or reactive power extraction technology to quickly analyze the harmonic or reactive power of the load current. Reactive power content, and then generate PWM pulses according to the set value, drive the bidirectional converter composed of three-level IGBT modules, and generate compensation currents that meet the requirements of the grid. The dynamic and accurate compensation of harmonic current or reactive current can be finally realized, and the quality of power supply can be improved.

Main functions
maintain receiving end voltage, strengthen system voltage stability
compensate system reactive power, improve power factor, reduce line loss, save energy and reduce cost
suppress voltage fluctuation and flicker
suppress three phase unbalance
compensate both inductive and capacitive loads to achieve PF0.99 and avoid less and over compensation
Fast Response :
Fast response is implemented by SVG modules.The SVGs in the SVGC show the advantage of the electronic power switch. In the legacy SVC, the thyristor only serves as a fast switch, but cannot implement high-frequency
Optimal solution to reactive compensation and three-phase unbalanced compensation
Integrating general LC compensation with the latest SVG compensation technology
Integrated Control & Monitoring System (ICMS)with 18 I/O ports to implement flexible LC and SVG applications
PF= 0.99, avoiding over-compensation and under-compensation


Technical advantages

• Compact design, the biggest module is only 0.05 cubic meter. High power density is more suitable for space-saving required project or updated projects.
• Designed with same industrial theory with high environment compatibility.
• Module control single board is IP6X which was passed the test of 3rd party China national lab.
• The output adopts the staggered parallel control method, which can reduce the ripple current by nearly 40%;
• Millisecond-level dynamic response, the full response time is less than 2ms, accurate tracking of transient current changes in the power grid, avoiding over-compensation and under-compensation
•  Industry-leading IGBT redundancy design, single-circuit failure does not affect the normal operation of the system;
• The equipment is completely disconnected from the power grid in the event of a fault, and there is no port capacitor hanging on the grid, so as to avoid resonance and leading reactive power effects on the power grid;
• Support CT connection on the power supply side or load side, which can be flexibly adjusted according to site conditions;
• With fast and complete fault self-checking function, it can be intelligently adjusted according to the on-site operating environment and status;
• More convenient maintenance features, bus capacitors, fans, etc. can be separated independently;
• Intelligent algorithm, automatically adjust the compensation ratio according to the real-time changes of reactive power and harmonics, and can also flexibly set the compensation target to achieve the optimization of the business target;
• Intelligent sleep, the parallel system adopts a round-robin mechanism to evenly distribute the working time of each module under low load and prolong the life of the module;
• CE,EN 62477-1:2012+A11-2014+A1-2017 ;
• Passed CE certification, in line with EN 62477-1: 2012+A11-2014+A1-2017 standard;

• APF can compensate 2~51 harmonics instantaneously, and the compensation range is larger;
• ASVG can compensate 2~23 harmonics, and the harmonic compensation capacity and reactive power compensation capacity can be set in full range;
• SVG can instantly compensate inductive reactive power and capacitive reactive power in full range, and solve the three-phase unbalance problem at the same time.

 High reliability and high performance

• The industry's first control layer dustproof module: effectively separates the control part and the power part, the control layer adopts a fully enclosed dustproof design, and there are no ventilation holes on both sides, front and rear to ensure good sealing performance; The main power components dissipate heat to ensure the heat dissipation performance of the equipment. The control layer reaches the protection level of IP6X, and has passed the experimental test of a third-party organization. Make sure that the external environment does not contaminate the control part. With the blessing of industrial-grade hardware design, the security and reliability are further improved.

     

• A more reliable IGBT independent control scheme is adopted. Each IGBT is equipped with a set of drivers and a Hall to ensure independent control of each IGBT power module. In the case of a single-sided IGBT failure, the device can still provide 50% of the rated output. capacity.
• A soft-start relay and soft-start resistance are set between the filter capacitor and the power grid to ensure that when the equipment fails, the filter capacitor is disconnected from the power grid and will not cause secondary effects on the power grid.
