In the event of system failure will stop and work to protect system security;Power supply with overheating, overload, overcurrent, short circuit, drive protection and other protection features to ensure reliable and stable power supply operation;3,The whole system of modular power unit design, replacement simple, fast, it can quickly troubleshoot, withoutaffectingthe entire system, with excellent electromagnetic compatibility, which canmeet the reliable application of various occasions;4,Support RS485, Ethernet communication, optional CAN to meet customer remote monitoring and other functions;Itcan display AC and DC voltage, current, mode of operation, operating status,Fault information, etc., and through the communication interface to upload the relevant data to the remote host computer, and through the host computer to start and stop the power supply, parameter settingsand other operationsTechnical Characteristics1,Bidirectional converter with V / F and P / Q two kinds of control mode, in the P / Q mode, according to the dispatching department command to control active power and reactive power transmissionoutput, with four quadrants full capacity operation capacity;2,Bidirectional converter with high efficiency, PCS is a high-frequency topology, the maximum efficiency is more than 95%;3,Bidirectional converter with oneethernet interface, one485 interface communicating with the monitoring system , free protocol text;4,Bidirectional converter and BMS communication interface for Modbus TCP / 485. Under the same conditions, the communication protocol will give priority to using the MESA energy storage protocol in the United States, supplyingcommunication protocoltext for free;5,Active power control functionBidirectional converter can control its active power output according to the monitoring system instruction. In order to realize the active power regulation function, the battery energy storage system should be able to receive and track in real time6,The active power control signal sent by the monitoring system is executed, and the active output is automatically adjusted according to the signal voltage on the grid-connected side and the control system control instruction to ensure thatthe maximum output power does not exceed the given value;7,Response at abnormal frequencyBidirectional converter with a certain ability to withstand system frequency anomalies;
IsolatedIsland operationBeside the on-gridmode ,the bidirectional frequency converter is alsowith island operation mode, that is, in accordance with thesettingconditionsgettingoff from the main network, in the capacity range for the part load to provide compliance8,Power quality requirements of power grid;Bidirectional converter protection
Bidirectional converter with DC overvoltage, undervoltage protection, overcurrent protection, reverse input protection, AC undervoltage / overvoltage protection, overload protection, overheat protection, over / underfrequency protection, three-phase unbalance protection and alarm, AC reverse phase protection and alarm function;9,Bidirectional Converter DC Power Quality RequirementsWhen charging,it can meetthe battery power quality requirements. Constant current charge, the steady flow accuracy ≤ 1% FS (20% to 100% of the rated output current);10, AC side voltage unbalanceAfter the converter is connected to the power grid, the unbalance of the three-phase voltage at the common connection point does not exceed the limit value of GB / T 15543-2008 "Three-phase voltage unbalance of power quality",the negative point of the common connection point voltage unbalance does not exceed 2%;
Bidirectional converter operating status visualization of a high degree. Touch screen as a man-machine interface. Through the touch operation, it can clearly show the real-timeoperation of the data, real-time failuredata, historical fault data;
