Hybrid Energy Control Module---HES7120-PV

HES7120-PV Hybrid energy control module is used in solar energy control system with inverter as output. It can control the closing and opening of the circuit breaker, start and stop of the inverter and the output power, etc.It can be set as fixed power, busbar control power and inverter control power mode, and display all data and status of solar PV power generation according to the system application.

Function and Characteristics

1、Collect and display three-phase voltage, three-phase current, frequency and power parameters of busbar/PV generation.

2、The busbar has the functions of over voltage, under voltage, over frequency, under frequency, loss of phase, reverse phase sequence, over power, reverse power and voltage imbalance.

3、PV generation has the functions of over voltage, under voltage, over frequency, under frequency, loss of phase, reverse phase sequence and voltage imbalance.

4、The voltage, current and power display of up to 4 solar panel channels can be set.

5、The maximum capacity of PV is calculated by collecting up to three solar panel temperatures and three solar panels illuminance.

6、A variety of temperature, pressure, liquid level, power transmitter, light radiation illumination sensor curve can be used directly.

7、Busbar power acquisition can be obtained by current transformer, power transmitter and communication.

8、With a variety of 485 interface protocol, it can communicate with various inverters with 485 interface.

9、With the function of normal automatic closing and starting with load, automatic soft loading and soft unloading.

10、With the minimum load power setting of the busbar to prevent reverse power transmission to the busbar.

11、With up to 6 busbar power sharing channels, and calculates the total load power of busbar in real time according to the state of input port.

12、It can realize automatic start/stop of PV generation inverter, close and open of circuit breaker switch and perfect fault display protection.

13、Three active power control modes (fixed power, busbar control power, inverter control).

14、Four reactive power control modes (fixed power, busbar control power, power factor, inverter control).

Hybrid Energy Control Test System

The test system is mainly composed of mains, diesel genset, automatic switching of dual power supply, photovoltaic power generation, inverter and hybrid energy control module HES7120-PV.

Description of Working Mode

1. In the manual mode, the inverter is started and stopped by the start/ stop key, and the inverter power circuit breaker is controlled by the close/open key.

2. In the automatic mode, when the busbar is normal, the inverter circuit breaker is closed and the inverter starts to output. When the busbar is abnormal, the inverter circuit breaker is opened and the inverter stops output.

3. In the stop mode, the inverter circuit breaker opens and the inverter does not output.

Note: During the conversion of mains and generation, the inverter circuit breaker shall be opened or the inverter power output shall be stopped; the controller can be set to prohibit ATS conversion.

PV Active Power Control Mode

1. Fixed Power Mode

Active power of constant output setting

2. Busbar Control Power Mode

Set the minimum load percentage ratio of the busbar, and the part exceeding the minimum load setting value of the busbar will be loaded by PV generation. The busbar control mode must be connected to the busbar CT or busbar power transmitter or other communication methods to obtain the busbar power.

3. Inverter Control Mode

The controller does not control the power output, but the inverter controls the output of active power.

Application of Multi Master Station Power Management Controller HMC6 in "Guangxiao 05" Ship

Three 175KW gensets are in the network, the load percentage is less than 30%, and the No.3 genset with low splitting priority is in the network

Recently, the power station of "Guangxiao 05" catamaran fire-fighting boat built by JiangLong Ship Building on the coast of the South China Sea has successfully passed the CCS acceptance. The successful acceptance of the automatic power station marks that the ship is one step closer to the mooring navigation test. The on-site commissioning personnel of Zhongzhi technology company will witness this exciting momentstogether with the project management personnel of JiangLong Ship Building, the manufacturer of main switchboard and the manufacturer of main genset.

Guangxiao 05 in Berthing State

The power management system is built by three multi master power management controllers HMC6 and its auxiliary expansion modules on the main distribution board. The system is set in manual and automatic modes, and the startup sequence can be adjusted arbitrarily. In automatic mode, three main gensets can be automatically synchronized and combined according to the priority, and can be automatically adjusted in frequency and load during parallel operation to quickly complete the balanced distribution of active power. When the genset is running with heavy load, the online genset will be increased, and when the load is light, the online genset will be reduced. When the online genset fails, the standby genset will start automatically and automatically start, and the failed genset will automatically exit. When a single genset fails and loses power, the standby main genset can start on its own and close within 30 seconds for power supply. The system can also automatically close and disconnect the disconnector between the busbar A and busbar B. The high-power side thruster has the function of heavy load inquiry, and the system has the function of automatically unloading the non-important load when the parallel operation of the main genset is overloaded.

With the help of HMC6 power management controller's built-in power management strategy and rich adjustable parameters, users can quickly realize the balanced distribution of active power and load distribution precision under the harsh conditions of any combination of three units, such as extremely fast synchronous parallel operation, different load percentage, sudden load increase and sudden discharge, etc. by modifying a small number of core parameters in a short time within 3%.

Introduction of the Core Functions of Multi Master Power Management Controller HMC6

Power Management Solution of HMC6 with HMC9000 Diesel Engine Control Box

The system builds a real multi master station system through MSC communication network (CAN bus), and its power management function is realized by the calculation of all generator control units. In the system, a control unit is selected as the "instruction unit", which is responsible for the calculation of the starting priority and other related power management functions of the genset. It can realize automatic synchronization and load distribution of up to 16 gensets. If one control unit fails, the power management calculation will be automatically transferred to the next available control unit.
