SmartGen | Parallel and Grid-connected Application of 10 Gensets

Customer demand:10 gensets are divided into 5 groups, two units of each group need to be connected in parallel. 5 step-up transformers boost 400V to 10kV respectively, 5 groups of generators are connected in parallel synchronously through 5 groups of bustie switches, and then connected in parallel with 10kV mains.

Unit Site

Solution:HGM9510 is selected for 10 gensets parallel, HGM9580 is selected for 5 groups of bus join cabinet, HGM9560 is selected for generator bus and mains parallel. Due to genset distribution room and diesel high voltage distribution room are too far, MSC communication selects CAN bus relay module SGCAN300 (CAN BUS to optical fiber).

Genset Parallel and Grid-connection Application

Working process:

1.When mains is connected to the grid, HGM9560 gen close/open key needs to be pressed manually to close load breaker, then schedule HGM9510 to start, HGM9580 automatically closes bustie switch synchronously at the same time, finally, gen and mains parallel synchronously, load outputs according to set active power output percentage by HGM9560.

2.When mains is abnormal, HGM9560 will automatically schedule genset to start; when gen close normally, HGM9580 will automatically close bustie switch in turn. After the external grid-connection/isolated grid knob is switched to isolated grid, load switch will automatically close, generator supplies power for load (generator takes all loads).

Debugging Site

After debugging, this application is completed successfully. The system is stably running, which wins customers’ praise.

SmartGen | Ordinary and Tenacious

It was the hot summer of 2019 when I first met Fu Ruirui.

I vaguely remembered the situation at that time, the head of HR told me that the girl who applied for the debugging position was very good and asked me to come for an interview.

When I got her resume, the first thing I saw was a line of beautiful fonts. But when I saw the major, I was very surprised. Normal university? Music major? Were you sure that the person recommended to me was the debugger? Fortunately, she had done debugging related work before, which slightly dispelled my doubts.

Looking at this gentle, elegant, quiet and indifferent girl, I decided to hire after in-depth conversation. She may be a good candidate if the company has activities in the future.


Not long after she joined the company, her mentor told me: “she is really good. She is very quick to learn and has a very strong learning ability. The most important thing is that she has a job in her eyes. She can do it quickly and well without my help , and she is very serious and careful. We should recruit more capable employees for our production line in the future.”

When you get to know her deeply, you will find that under the gentle and elegant appearance, she is actually a workaholic. Before 8 o’clock in the morning, she is busy in the workshop. Before everyone go to work, she starts the day’s preparation work: opening the test bench and confirming the equipment status in advance; Preparing the SOP files, test lines, test tools, etc. of the first batch of streamline products according to the planned sequence; Then doing the 5S work on site. When other employees arrive at their posts one after another, she has already finished the preparatory work, and is waiting for working.

Slowly, the colleagues around her will unconsciously follow her to start the preparations before going to work. I think this is the power of example. The world will live up to every persistence and effort. In just one year of joining the company, she was selected as the company’s annual “benchmark employee”.

Usually, I can often hear everyone calling her to help confirm the product, check whether there is any problem with the test line, and arrange for support. At this time, you can always hear her crisp response, tirelessly solve one problem after another, never say tired. I once asked her, “don’t you feel bored with these trivial and meticulous work every day?” “No,” she said. “I love my job. I just think about how to do it well.”


From the staff to the group leader, from the group leader to the line leader, she has taken every step steadfastly and firmly.

From the preliminary test to the outgoing quality control, she is mainstay of the outgoing quality control process.

There are many stories about her, which will not be earth-shaking, and it sounds very ordinary just like the ordinary people around us. But excellence is never something to say. Excellence is created by accumulated efforts in those ordinary days. Excellence is to accept the ordinary, and then go all out to be outstanding in the field you love.

Ordinary and tenacious shines in her daily work and lasts in the long river of years.

SmartGen | Genset Cloud Monitoring FAQ

SmartGen cloud monitoring modem can be connected to SmartGen cloud server (SmartGen Cloud Plus) via GPRS, network, WiFi to realize genset remote monitoring.

Cloud Monitoring Solution

A few days ago we found that some customers could use cloud monitoring normally when the unit was commissioned, but it did not work properly after it was sent to the site.The following common causes and solutions are specially sorted out for your reference!

─The controller communication address is changed by the customer on site, resulting in inconsistency with the unit communication address set in the background, making it impossible to communicate. The performance of fault is cloud modem RS485 light is always on, GPS and GPRS lights are flashing, power light is always on. This is a more frequent situation, be careful not to change controller communication address at will.

─Field controller 485 wire is unplugged, making communication impossible.

─GPS cannot position—the phenomena is that positioning has been the previous address, other data are normal, but cloud modem GPS light is always on. At this time, you can check whether there is a problem with GPS antenna connection.

─IOT cards are reused. Under the current rule, the IOT card can only match one cloud modem or integrated controller. If IOT card is activated for use in the first device and then inserted into another device for use, it will cause card locking to fail to communicate. In this case, you can put the card into the original device and wait for it to be unlocked or report to the IOT card vendor to re-bind the card with the new device. Remember that one card can only be used on one device in order to avoid locking. Do not use one card for multiple purposes!

─IOT card is normal but cloud modem cannot communicate. At this point may be the card is not correctly inserted, you can try to reinstall the card. Pay attention to whether the card slot is in good condition and can be closely combined with the card.

More questions continue to be collected and summarized. SmartGen, making control easier!

SmartGen | HGM9560+HGM9510 Methane Power Control in Jiangsu Farm

Methane power generation is methane utilization technology that emerged with the continuous development of large methane tank construction and comprehensive utilization of methane. It applies methane produced by anaerobic fermentation treatment to the engine and is equipped with an integrated power generation unit to generate electricity and heat. The methane power is beneficial, energy-saving, safe and environmental, which is a cheap distributed energy.

This time the customer comes from a large dairy farm in Jiangsu, using methane to generate power. The site adopts two 250kW gensets using HGM9510 to parallel.

Power Control Site

The customer uses HGM9560 mains control mode at the same time, which can realize the distribution of genset and mains load power and unit load power via setting mains load percentage, thus realizing grid-connection without on-grid.

Set two HGM9510 as “Start on Demand” and “Balanced Running Time” to realize single unit running under low load mode and two gensets run in turn under long-time low power running mode.

HGM9510 is equipped with cloud monitoring module CMM366B-4G that can monitor genset data in real time and record power accumulation and accumulated running time via mobile APP and PC version “SmartGen Cloud Plus”.
