Certifications

The Power Energy Storage Converter Module (Power Conversion System- INPPCS) meets the following standard:

IEC-62477	Safety requirements for power electronic conversion systems and equipment
IEC-61000	Electromagnetic Compatibility (EMC)

Funtions of Model:
1 Basic functions
(1) The PCS converter realizes AC/DC conversion between the power grid and the battery, and completes bidirectional energy flow;
(2) It adopts a three-phase four-leg topology and can control the single-phase, three phase active, and reactive power;
(3) It supports multi-machine parallel connections with good scalability;
(4) It supports active and reactive power regulation;
2 Advanced functions
The PCS, in conjunction with the EMS controller, enables the following advanced application functions:
(1) Peak load shaving: The EMS controller calculates the power expected value of the PCS according to the historical curve or the real-time load curve, and the PCS output responds to the power value to realize the function of "peak load shaving";
(2) PCS module charging and discharging control function: the EMS controller can determine the charging and discharging state of the PCS module and the charging and discharging current according to certain control strategies and the battery information returned by the BMS; the PCS can receive and execute the charging and discharging instructions sent by the EMS controller, and it also can receive the BMS instructions.
(3) Reactive power regulation: The PCS module can adjust the reactive power output according to the control commands by the EMS controller, and the reactive power regulation does not exceed the range of the apparent power of the PCS module.
(4) The response characteristics when the frequency is abnormal: the inverter can withstand system frequency abnormalities to a certain extent.
(5) PCS protection function: PCS provides real-time fault protection based on the voltage and frequency at the grid-connecting side and the operating status itself, including:
Overvoltage and undervoltage protection of the power grid
High and low frequency protection of the power grid
DC overvoltage/undervoltage protection
DC overcurrent protection
DC polarity reverse protection
AC overcurrent protection
Overtemperature protection
