　　Product Overview

　　Definition and Positioning

PCS6000: Full power converter (Power Conversion System), used to convert direct current generated by renewable energy (such as wind power, photovoltaic power generation) into alternating current, or to achieve two-way energy exchange between energy storage systems and power grids. Applicable to megawatt-level high-power scenarios, emphasizing high reliability, high efficiency and grid compatibility.

　　Core application scenarios

Wind power generation: connect wind turbines to the grid to achieve maximum power point tracking (MPPT) and low voltage ride-through (LVRT).

Photovoltaic power generation: adapt to large photovoltaic power stations, support centralized or string inverter solutions.

Energy storage system: as the core equipment of the battery energy storage system (BESS), it realizes charging and discharging control and grid peak and frequency regulation.

Microgrid: coordinates the energy management of distributed power sources and loads in off-grid or grid-connected mode.

Onshore/offshore wind farms: as the interface between wind turbines and the grid, improve wind energy utilization and grid stability.

Photovoltaic power station: used for centralized photovoltaic inverters to achieve maximum power point tracking (MPPT) and grid-connected control.

Energy storage system: combined with battery energy storage, it realizes peak shaving, frequency regulation, backup power supply and other functions to enhance grid flexibility.

Microgrid and distributed energy: support multi-energy complementarity (such as wind, solar and storage integration) to achieve autonomous operation of local power grids.

　　Technical specifications and performance parameters

　　Power level

Typical power range: 1MW-10MW

Electrical parameters

　　Input side (DC):

Voltage range: 600V-1500V DC (adapt to different photovoltaic modules or wind power converter output).

Maximum input current: depends on the power level (such as 5MW models may support ≥3000A).

　　Output side (AC):

Voltage level: medium voltage (10kV/35kV) or low voltage (400V), matching grid access requirements.

Frequency: 50Hz/60Hz adaptive, supporting global grid standards.

Power factor: ≥0.99 (adjustable), meeting reactive power compensation requirements.

Total harmonic distortion (THD): <3%, in line with IEEE 519 standard.

　　Efficiency and reliability

Peak efficiency: ≥98.5% (European efficiency standard), reducing energy loss.

MTBF (mean time between failures): >100,000 hours, adapting to harsh environments (such as deserts and coastal areas).

Protection level****: IP54/IP65, dustproof and waterproof design, supporting outdoor installation.

Cooling method: liquid cooling or air cooling optional, adapting to high temperature/high altitude areas.

Core functions and technical features

　　Intelligent control algorithm

Maximum power point tracking (MPPT): dynamically adjust the working point to improve power generation efficiency (wind power/photovoltaic scenarios).

Low voltage ride-through (LVRT): keep connected to the grid when the grid fails to avoid power fluctuations caused by disconnection.

Power regulation: support active/reactive independent control, participate in grid frequency and voltage regulation services.

Black start capability: When the power grid is completely out of power, the energy storage system is used to restore power supply (microgrid application).

　　Modular design

Power module: IGBT/SiC devices are used, hot-swappable, and easy to maintain and expand.

Control unit: Distributed architecture and redundant design improve system availability.

Communication interface: Support IEC 61850, Modbus TCP, DNP3 and other protocols, integrated into SCADA or energy management system (EMS).

Power quality optimization: Improve grid stability and reduce harmonic pollution through active/reactive power control.

Grid-connected control: Support low voltage ride-through (LVRT), high voltage ride-through (HVRT) and other grid fault response capabilities.

Bidirectional energy flow: Applicable to energy storage systems to achieve flexible switching of charging/discharging modes.

Environmental adaptability: Designed to meet stringent industrial standards (such as IP54 protection level, vibration/shock resistance).

　　Full power conversion

Convert the AC power output by the generator (such as a wind turbine) into DC power, and then invert it into AC power that meets the requirements of the grid to achieve flexible connection with the grid.

Supports bidirectional power flow, suitable for grid-connected and off-grid modes.

　　Power quality control

Power factor correction and harmonic suppression are achieved through advanced control algorithms (such as vector control and direct torque control) to ensure that the output power meets grid standards (such as IEEE 1547, GB/T 19964).

　　Fault ride-through capability

With low voltage ride-through (LVRT) and high voltage ride-through (HVRT) functions, it maintains grid-connected operation when the grid voltage fluctuates and avoids disconnection.

Reactive power support

Dynamically adjust reactive power to improve grid stability, especially in weak grid environments.

Grid adaptability

Wide voltage/frequency range: adapt to grid fluctuations (such as voltage deviation ±15%, frequency deviation ±2Hz).

Harmonic suppression: built-in filter to reduce pollution to the grid.

Anti-islanding protection: Quickly disconnect after detecting power failure of the power grid to ensure personnel safety.

　　Installation and commissioning
