Featured with simple power plant construction, small investment, lower cost to output every kilowatt compared with power plants driven by gas turbine and steam engine thanks to mature technology of internal combustion engine.
4. 机组运行灵活。可单台使用，也可多台组合使用，可并机，也可并网；可根据用户自身实际用电负载的需要控制发电量大小，并可根据实际用电负荷的差异，随时调整运行机组的数量，有效利用设备资源，减少运行成本�?/DIV>
Designed with flexible operating method, the generators set can be applied independently or in parallel with other generator sets or to be connected with public electric grid by means of ysnchronization. Based on the different demands for electric load by the consumers in fact, the quantity of generator sets in operating or to be put in operation shall be adjusted to control power output in order to make these equipments much more efficient and decrease the operation cost.
5. 从机组启动到并网发电速度快，短时间内可完成全部过程，实现并网或独立发电�操作简��，普通工人经过短期培训就能熟练掌握�与其他燃气发电方式相比，调峰性能最���?/DIV>
It only takes a very short time for the generator set to fulfill the complete procedures from starting into public electric grid. The generator set shall be connected with electrical grid or generate electricity independently. Because of easy operation, an ordinary operator can be skillful to operate it after short time training in general. Compared with other method of power generation, the generator set achieves a best peak load regulation.
6. 机组大修周期长，维护时间短，维护方便，运行平稳，运行人员少�由多台机组组成的发电站可长期连续运行供电，电力输出更有保障�
The generator set is feathered with long period of overhaul, a short time for maintenance, reliable operation and it needs only a few of operator for operation. When a power plant is equipped with several generator sets, it may operate continuously and output electricity power reliably.
7. 机组可维护�强，所��问题均可以由操作维护人员在现场解决�
For it is convenient for maintenance ability all of troubles related with the gen-set can be removed or fixed by operators or technicians on site.
8. 水消耗量小，更�合干旱缺水地区�
The generator set shall consume a small amount of water so it is suitable to be applied in droughty area or region lack of water resource.
9. 主要控制零件部分如调速器、点火系统等，均采用世界知名品牌产品�?/DIV>
The critical spare parts or components are introduced from international renowned brands such as speed governor, ignition system etc.
10. 机组的各种保护系统齐全�
The generator set is installed with complete protection systems.
