SmartGen案例 | 现场直击——多机并联并网控制应用最新案例集锦

案例一：2台HGM9510高压并机

某单位用电设备为10.5kV，市电停电后需要备用发电机组给负载供电,负载容量较大单台机组功率达不到，需要2台高压机组并联使用。HGM9510可以高压机组并机，只需把控制器的电压互感器功能打开，设置好电压互感器的变比即可，HGM9510控制器根据电压互感器变比显示发电机组实际电压。

案例三：HGM9520N机组并网不间断供电

HGM9520N市电并联控制器，配合国家电网使用负载接收模式并市电，给某工厂不间断供电。工作逻辑为：停电前机组开机并到市电上，发电软加载，市电功率全部转移到机组上，市电分闸停电，机组单独带负载运行。市电恢复正常后机组反同步市电，市电合闸发电功率全部转移到市电，机组分闸停机，市电单独带负载。

案例四：HGM9560+HGM9510燃气并网

绍兴某纺织厂因工厂负荷过大，使用燃气并网供设备正常工作，现场使用一台500kW燃气机组和市电并网供3条流水线工作。使用市电管理模式，市电带40kW负载，其余负载全部由燃气机组负责。现场车间和机房距离比较远，使用SGCAN300光纤模块通讯，机房HGM9510控制箱侧配一台SGCAN300模块，配电室配一台SGCAN300模块，完美解决远距离通讯问题。

Case | Latest Multi-set Parallel and Grid-connection Application

Case 1: 2 HGM9510 for high voltage parallel

A unit with a 10.5kV power supply requires a standby genset to supply the load after mains power failure, but the load capacity is too large for a single set to reach, so two high voltage sets are needed in parallel. The HGM9510 can realize high voltage parallel, simply turn on the voltage transformer function of the controller and set the voltage transformer ratio, then HGM9510 controller will display genset actual voltage according to the voltage transformer ratio.

Case 2: 16 HGM9510 for combustion engines parallel

The HGM9510 is used in a project where 16 combustion engines are paralleled by a Huachai DEUTZ gas engine with a Maidi generator, achieving perfect paralleling on site. HGM9510 realizes speed regulation through analog, engine monitoring through CAN, and fast power sharing through MSC communication.

Case 3: HGM9520N grid-connection and uninterrupted power supply

HGM9520N mains parallel controller, in conjunction with the national grid using load receiving mode and mains power, to supply uninterrupted power to a factory. Working logic: Before power outage the unit is started and connected to mains, the power generation is soft loaded, all mains power is transferred to the unit, mains power is switched off and shut down, the unit runs with load alone. After the mains power is restored to normal, the unit is anti-synchronous to the mains, mains power is switched on and all the power generated is transferred to the mains, the unit is switched off and shut down, and the mains power is loaded separately.

Case 4: HGM9560+HGM9510 gas grid-connection

A textile factory in Shaoxing uses a 500kW gas unit and mains power grid-connected for the normal operation of three assembly lines due to the overload of the factory. The mains management mode is used. Mains takes 40kW load and the rest of the load is all taken care of by the gas unit. The distance between the on-site workshop and the machine room is relatively far, so SGCAN300 optical fiber module is used for communication. One SGCAN300 module is equipped on the side of the HGM9510 control box in the machine room, and the distribution room is equipped with the other SGCAN300 module, which perfectly solves the long-distance communication problem.
