SmartGen’s blog

Our national people's efforts to fight against the novel coronavirus during the crucial stage of epidemic prevention and control are still vivid in our's mind. Saluting our lovely medical workers and the dedicators who work outside in order to early achieve the victory against the epidemic... They work day and night, racing against the clock that timely build protective barrier for us with full of love.

Chinese people have united together and made great contribution to early realization of anti-epidemic victory when facing the challenge. As a affectionate member of Chinese enterprises, SmartGen also devotes to the special needs of motherland and serves the society to its best with practical actions.

Since the outbreak of the epidemic, we have opened 109 cloud monitoring units for users free of charge and sponsored more than 100 modules, so as to realize remote monitoring of gensets without going out. We have made contributions for fighting against the epidemic and reducing outdoor activities like Zhengzhou Xiaotangshan, Wuhan Huoshenshan, Beijing Xiaotangshan......

At present, the epidemic has been well controlled in China, but the awareness of prevention and control cannot be relaxed. We will continue to dedicate our love and efforts to fight against the epidemic for our industry and our motherland. The sponsorships are still going on, and what you need is what we're willing to stick with; don't ask me why there are tears in my eyes, because we are a family!

Fighting together for early victory!

Fighting together for better tomorrow!

Fighting together for meeting soon!

SmartGen has been involved in marine diesel control for 10 years.

We have devoted a lot, but compared with land-based genset control , the marine diesel control business doesn't perform well.

Over the past decade, we have come to understand that both the market and ourselves are not mean to defeat with but to get along with each other. Some things do not make sense, but we must believe them; some beliefs are not strong at first, but we still have to rely on them. Then prove it with action and stick to firmly!

In the past ten years, the machine diesel control products have been upgraded and optimized for many times and are becoming better and better. The process likes life, some rain is bound to fall, some days are painful indeed; however, there is no incurable pain, no end of the destruction. All the lost will be back in other way.

Good news of marine diesel control products coming from abroad recently. Italian luxury yacht was equiped with SmartGen power control system. When talking about yachts, the first to think of "Ferretti" yacht group, which is not only the largest in Italy, but also the largest luxury yacht design and manufacturing company in European; Italian yachts have been leading the trend of modern yachts with romantic, luxurious, elegant and other styles.

The yacht was powered by two MTU 12V engines:

Two marine diesel control modules of HMC9000A of SmartGen were applied:

Two 8-inch touch screen remote monitoring control modules of HMC9800RM were used in drivingConsole:

In addition, the yacht was equipped with 19kW and 22kW gensets respectively, the automatic power supply switching of two gensets (dispatching, balancing, main and standby operation modes) and shore power were realized by HAT832 (three power ATS control module).

The system solution is as follows:

Silently cultivate and spare no effort; where there is real ability there is fame.

With this common encouragement!

Ten years looking back with full of emotion!

This case involves the use of SmartGen's HGM9510 parallel control module that can realize multi-units parallel connection; HGM9560 multi-units grid-connection control module can realize parallel connection of power generation and mains supply. With the cooperation of the two, it can meet the requirement of multi-units parallel connection and grid-connection with mains supply, realizing the application of the constant power output and the shear peak of the units.

The operation data of the two units are as follows

The first unit, accumulative power: 1204.4 MWH; power factor: 0.89; accumulative running time: 10,528 hours.

The second unit, accumulative power: 795.4mwh; power factor: 0.77; accumulative running time: 10,528 hours.

Grid-connection diagram of the two units

Constant power output: the maximum active power output of the genset is what the setting active power output of the geneset. When the gensets and the mains supply are connected in parallel successfully, the power generation begins to output the load. When the active power output of the power generation reaches 100%, the remaining load is carried by the mains supply, which can also be considered the power generation as main use. When the load is less than the setting value of active power output of the power generation, the mains supply begins to soft unload tripping.

Mains supply shear peak: mains supply first starts with load, when the active power output reaches 100% of setting value, the control module is in automatic mode, gensets start automatically, closing and paralleling with mains supply after normal operation, units start soft unloading, receiving the rest of load, when the load is lower than the setting value of active power output of mains, the units stops for soft unload tripping.

In the previous two chapters, we respectively introduced the powerful display features of HGM9420N/LT (with 16 built-in languages) and various extended functions. This chapter we will introduce the single unit control module's special synchronization switching features, as well as the communication protocol customization, NEL (non essential load), dummy load, cloud monitoring and other functions.

The single unit automatic system composed of one mains supply and one genset could realize the synchronous swithing beween power generation and mains supply, which decreases the power supply interruption to a great extend caused by power generation and mains switching.

Operation Description

Automatic start/stop

Press button, the indicator lights on, indicating that the genset is in automatic startup mode.

Automatic start:

a) Mains power is normal and remote start (on-load) is effective, the unit high-speed warming-up delay ends, the indicator lights on if power generation is normal, the control module sends out switch-on signal when gensets and mians power meet the synchronization requirements, while sending out the switch-off signal immediately after detecting power switching feedback signal, then genset is on-load.

b) When the mains power starts abnormally and high-speed warming-up ends, the indicator lights on if the power generation is normal. If the voltage and frequency meet the requirements of on-load, the power generation closes and relay outputs, the genset is loaded, the power supply indicator lights on and the genset is in normal operation.

Automatic Stop:

During the normal operation of the genset, if the mains power returns to normal, then enters the "mains voltage normal delay". Make sure the mains power is normal, the indicator of mains power status will be on, the "stop delay" will begin. For another case, when the remote start input fails, “stop delay” starts.

The control module waits for gensets and the mains power to meet the synchronization requirements, it will send out the mains power closing signal. After detecting the feedback signal of mains power switch-on, it will immediately send out the mains power switch-off signal, the power supply indicator lights off, the mains power is on-load, the mains power supply indicator lights on, and the "high-speed heat dissipation delay" begins to enter the shutdown process.

The conversion flow chart is as follows

Synchronous switching typical application diagram

Note: Breakers (such as frame circuit breakers) that can close simultaneously should be used.

Parameter settings

Note: the control module shall be set and conected the auxiliary contact signals to power generation switch closing and mains power switch closing, so as to judge the position state of switch-on and switch-off.
