HMP300-2 Power Integrated Protection Module was used for the main distribution board of 50000DWT Bulk Cargo Ship
HMP300 power integrated protection module is a high-performance control module developed by SmartGen in combination with the design requirements of marine power distribution system, which integrates the measurement and collection of parameters such as voltage, current, frequency, power and power quality of the generator, abnormal protection and communication transmission functions. It has been certified by CCS and was widely used in marine and land power distribution.
This series of module can be configured at the most four programmable output ports and and two programmable input ports, the designers with a HMP300 control module can reach ever need voltage protection, current protection, reverse power protection and frequency protection and voltage/current harmonic distortion rate and the electrical parameter collection that may kinds of single function module to achieve technical index, can protect diesel gensets, axle gensets and emergency gensets, significantly increase the system integration and cost-effectiveness ratio of AMS and the PMS system structures.
The harmonic detection function of HMP300 series control module
There are two submodels HMP300 and HMP300-2 designed for users to better meet different technical requirements:
HMP300 is equipped with a communication interface supporting CANBUS2.0B protocol, which is mainly used to communicate with the marine engine control module of SmartGen to achieve power data acquisition and display; The model also has differential protection, which can be used to protect the three-phase leakage current of generator or motor.
Differential Protection Mode of HMP300
HMP300-2 is equipped with RS485 interface supporting Modbus-RTU communication protocol, which is mainly used for generator and bus protection and transmission of information to the main logical control unit, and supports the function of customizing Modbus-RTU communication protocol. In addition, HMP300-2 is specially optimized for the protection of steady-state frequency fluctuation and transient frequency fluctuation of the axle geneset. Users only need one HMP300-2 to protect all the electrical parameters of the axle genset.
The backlight LCD (132x64) on the module can visually display the values of various electrical parameters and alarm information, and supports display Chinese and English. Users can switch the display interface and modify the core configuration parameters by touching the button.
Technical parameters of HMP300 series control module
Application example of HMP300-2 protection shaft belt genset
To help you better understand the design concept of the module, the following are some examples of parameters of HMP300-2 used in the protection projects of shaft belt genset: AC400V50Hz, 450KW, steady-state frequency fluctuation ±5.5%, 10s; transient frequency fluctuation ±11%, 5s.

---HGM9420N/LT
In the previous four chapters, we respectively introduced the powerful display functions of HGM9420N/LT (with 16 built-in languages), as well as various extensions, synchronization switching, communication protocol customization, NEL((non essential load), dummy load, cloud monitoring, PLC, etc. This chapter we will introduce the functions and application methods of USB interface.
There are two kinds of USB interfaces of HGM9420N/LT. The USB drives in FAT32 format can be inserted through the Host USB interface to achieve the following functions.
Input or output of configuration parameters
1. Press 
for more than 1s，then go to user menus of the following table.
2. Select the USB flash drive configuration with reading and writing, which could check, download, save and renew the configuration file.The configuration file suffix is.lgm.
3. Check the xxx. lgm configuration parameter file in the USB flash drive.
4. Download the configuration file in HGM9400NXXXX. lgm format to the control module.
5. Save the control module's configuration parameters to the corresponding HGM9400nxxx.lgm file.
6. Renew configuration file(HGM9400NXXXXX.lgm).
Historical Data Storage
The historical data is stored with year/month as the folder name and year/month/day as the .dat file name. The unit stores data once per minute in standby mode and once per second in other states. If the storage space of USB flash drive is less than or equal to 200MB, the earliest one-month data files stored will be deleted.
The historical data files are shown as below.
Curve of historical data
The curve of historical data could be checked and viewed by the "data analysis" function of iGMP6 test software.
In the previous chapters, we have introduced the main functions of HGM9420N/LT. If you have any questions or further demands of the control module, please feel free to contact us!
Go, genset control!
Go, China!
