SCO Qingdao Summit,China Unicom Meets SmartGen

From June 9-10, 2018 ,the 18th Meeting of the Council of Heads of Member States of the Shanghai Cooperation Organization was held in China’s beautiful coastal city of Qingdao, it is called “SCO Qingdao Summit”. The SCO has been founded for 17 years and once again it returned to China. The green city Qingdao,it is suitable for the holding of SCO. Hoist the sail when the wind is fair!

China Unicom is one of the three major telecommunication operators in China and China Unicom Qingdao branch provides an important guarantee for the communications security of SCO. As the generating set control, ATS control supplier and maintainer of China Unicom Qingdao branch, SmartGen was honored to join the SCO with them to provide a powerful guarantee for the normal operation of the communication backup power supply.

The 2500A ATS control cabinet produced by SmartGen is put into use before the meeting begins.It ensures the fast and safe switch between the mains and gens of Qinling Road sub-office of China Unicom Qingdao branch.

In China Unicom Qingdao branch the 1st communication hub (Shandong Road) and the 2nd communication hub, all support personnel were on standby 24 hours a day. The staff patrolled ATS control cabinet, diesel generating set and other power supply equipment regularly.They also started the generator set to test regularly, these was done to ensure the power supply and ensure that the genset can start quickly in the first time in mains power failure.

In a sub-office of China Unicom Qingdao branch,the generator set automatically started and was put into operation in mains power failure, providing a timely power supply support for the communication power of the summit.

During the meeting,the support personnel of China Unicom and SmartGen stayed in their posts all the time. Although they did not appear in the meeting place, they are behind-the-screen heroes! It is through their hard work that we can ensure the normal communication during the meeting and SCO Qingdao Summit is more wonderful because of them!

Can Your Genset Accelerate to High-speed Running? Come and See!

A customer in Tonghua, Jilin province told us that their gensets couldn’t accelerate to high-speed running. The customer adopts that one HGM9510 control module parallels with two 300KW gensets. The technical staff of SmartGen went to Tonghua to test on site. The result is that the gensets can’t accelerate to high-speed running, “idle speed control” output and warming up delay are normal. After checking GOV, our staff found that warming up delay is only 30s when the acceleration time is biggest. After warming up delay, the acceleration time delay of GOV is still not finished, so the gensets couldn’t accelerate to high-speed running.

Solution Reduce the acceleration time of GOV and start, the warming up of gensets is normal.

We summary some failure checking and solutions in case other gensets can’t accelerate to high-peed running: 1. Check if the idle control output of control module disconnects after idle timing. 2. Check if the GOV has failure and connections. 3. Check if the“rated speed”of GOV is too low. 4. Check if the acceleration time of GOV is too big.

Attention, Everybody, Small Problems Could Make Big Troubles!

A natural gas booster station in Yulin, Shanxi province,

adopts one HGM9310CAN control module and two AIN24 analog input modules cooperating with Perkins gas genset 800kW.

Failure the customer told us that the inlet/outlet temperature of the cylinder sleeve, the mixture gas temperature of A/B side pipe of genset do not display (sometimes display when stop).

Solution After checking, we found that the positive pole and negative pole of the charger are directly connected to the control module. When the charger works, the signal is disturbed. So we connect the positive and negative pole of the charger directly to the positive and negative pole of the battery group. Then the temperature signal of the genset display normally, the temperature when genset start, stop and run also display normally .
