First of all, Secretary-general Ren Xiaojun made a working report to the Mobile Power Station Technical Committee, proposing the goal of strengthening academic exchanges, improving industrial technology development, accelerating the technology research and development of energy conservation and emission reduction.

Then, Mr. Liu fugang, Director of China Electrotechnical Society, delivered a speech and pointed out that this meeting was an academic event, emphasizing that scientific and technological progress is the driving force to drive the development of the industry, so we need to rely on the special committee as an academic platform. He also put forward the vision that the committee will become a fertile soil for talent cultivation, the team of experts should be continuously expanded , and the committee had better to provide more industry standards for everyone to use and test.

New committee members were elected:

Mr. Li Kemin, a senior expert in the field of communication power supply, made a detailed interpretation and analysis of China’s 5G commercial first year era and the demand for power supply, which strengthened the participants’ confidence in the industry development and thought about business opportunities in the future.

Industry expert Mr. Wang Shouxi made a comprehensive and in-depth analysis of “reliability design of geneset control”.

The “dynamic visualization diagnosis technology of diesel generator set” Shared by Mr. xiao Jianjun of Foguang Electrical Power Equipment Co., Ltd provided strong data support for the verification of geneset.

Running into the “cloud monitoring” era, General Manager Mr. Xiongzhi from Chengdu Teslayun Co., Ltd shared the latest functions and prospects of cloud monitoring.

All members initiated “implementing national standards, protecting property rights, and purifying the market” and signed name jointly; At the same time, called on more enterprises and units to join the action of using legal version and resisting piracy.

Finally, all the leaders and friends went to” internal combustion power generation intelligent control system industrial park of SmartGen” to lay the foundation for the new factory, affirmed recognition the achievements of SmartGen has made and expressed good wishes for the future development.

Congratulations on the success of the special committee meeting! Congratulations to SmartGen being the co-organizer of this special committee meeting. Thanks to all the leaders and members of your concern and support for Smartgen all the time!

Two-line One Bus Tie Solution – HAT821

HAT821 dual power bus tie controller is mostly used in the switching system of two-line and one bus tie. It can detect the voltage and frequency of two lines, judge the normal and abnormal conditions of them, and automatically execute the operation of three circuit breaker switches according to the main setting.

1. HAT821 advantage 1 Compared with the traditional automatic bus transfer device. Do not need to separate the manual-automatic button, directly switch between manual and automatic mode on the pannel; Do not need to lead out multiple closing and opening buttons separately. There are 6 buttons on the controller directly control the closing and opening of the circuit breaker; Reducing the complex wiring and making operation simpler.

1. HAT821 advantage 2 Intelligent power supply switch inside the controller. The circuit breaker switch power supply is normal as long as there is a normal voltage; Provide AC 220V operating power supply for circuit breaker directly; L0, N0 power output capacity is 16A, which can ensure the normal power supply for circuit breaker switch.

1. HAT821 advantage 3 Automatic control function, three kinds of automatic logic are available for users. (S1,S2 mainly used): both channels are mainly used. When both power supply are normal, the two-line circuit breakers close the power supply respectively, and the bus tie is in the breaking state. When there is one abnormal switch, another switch and bus tie switch close to supply power for two loads; (S1 mainly used): one channel is maily used, (S1) one channel is normal, one breaker and the bus tie switching the power supply, when one is abnormal and two voltage is nomal, (S2) 2 switches and bus tie switching power supply; (S2 mainly used): two channels are mainny used, (S2) two channels are nrmal, two breakers and bus tie switching the power supply, when the two channels are normal and one votage is normal; (S1) one breaker and bus tie switching power supply.

1. HAT821 advantage 4 Multiple communication interfaces. It has a d-type USB communication interface, which can be used to connect PC to test software configuration parameters and upgrade module programs; It has two RS485 communication ports, which can not only realize the centralized monitoring “three-remote” function, but also realize the connection with the web of things and realize the cloud monitoring function.

User application cases

Application occasion: the project is applied to a large chemical enterprise. Application mode: (S1,S2) two main modes in the site. When both power supply are normal, the two-line circuit breakers close the power supply respectively, and the bus tie is in the breaking state. When there is one abnormal switch, another switch and bus tie switch close to supply power for two loads. Electrical interlock: Two sets of normally closed auxiliary contacts of the circuit breaker are used to realize electrical interlock. On the basis of controller logic interlock, another layer of electrical interlock is added to realize the dual protection of controller logic interlock and electrical interlock. Tripping fault: when the circuit breaker overflows tripping, the fault output signal controller detected by the circuit breaker will display the alarm of “switch tripping fault”, and switch from the automatic bit to the manual bit, no longer output the closing command. This function avoids the circuit breaker overcurrent trip, re-closing the damage to the circuit breaker.

In the past two years, we have continuously developed bus controller, three-power ATS controller, dual-power bypass controller and so on. we will continue to make efforts to focus on solutions of complex systems, and develop products such as three-line and one-bus, three-line and two-bus, etc. we will continue to update the products according to your valuable advices and requirements for application use are welcomed to improve our product lines.

Parallel Projects of 48 Gas Units –HGM9580+HGM9510 Power Station System Solutions

Recently, a gas power station project with total 48 gas units in Xinjiang was successfully delivered and put into use. During which the HGM9580 bus parallel control module and HGM9510 multi-machine parallel control module of SmartGen were applied in this control system.

For the power station or the complex system of multi-stage bus, using HGM9580+HGM9510 can realize the parallel connection of up to 512 geneset units, and realize intelligent scheduling, load sharing, non-important load tripping and other functions.

48 Genset Units Parallel SLD (Single Line Drawing) of A Power Station in Xinjiang

HGM9580 bus and bus parallel control module is suitable for manual/automatic parallel system of multiple gensets bus and mutiple gensets bus. The controller synchronizes two busbars through MSC CAN bus. When the synchronization condition is satisfied, the bus connection switch closes and the two busbars run in parallel.

HGM9510 genset parallel control module is used for the parallel system of multiple gensets of the same capacity or different capacity, as well as for the constant power output of a single genset and grid connection with the mains supply. The control module has the control functions of GOV and AVR, and can automatically synchronize and load sharing. This power station project only uses the multi-machine parallel function of HGM9510.
