Load factor, reducing the number of units running. 80 %可调)时,自动解除一台机组的运行;再次根据上述原则判断是否需再减一台机组运行;依次 When the load is less than 80 % of the total rated power of the unit , it can automatically cancel the operation of one unit; once again, it is judged whether another unit needs to be operated according to the above principles; Analogize until the remaining crew cannot be reduced. If the load increases during operation, the principle of adding machines is as follows: When the load exceeds the current operating unit 85 %(可调)时,自动再启动一台机组,投入并联供电。 When the total rated power is 85 % (adjustable), another unit is automatically started and the parallel power supply is started.

Load rate, reduce the number of unit operation. When the load is less than the units total80% of rated power adjustable), automatic lifting of a unit operation; again according to this principle, to determine whether it is necessary to cut a unit operation ; followed by analogy, remaining until the unit cannot be reduced. If during operation, load increases, add machine principle is as follows: when the load exceeds the current operating units total 85% of rated power (adjustable), automatic restart a unit, input parallel power supply.
