    G驱动发动机功率标定使用准则

    以下准则阐明了确保G驱动发动机应用于交流发电机组的正确使用规范。G驱动发动机并不是为 变速的直流发电机组而设计的,也不是作为直流发电机组的动力来使用。

    一、备用功率标定 是在市电出现异常时作 为应急电源使用时的瞬时最大功率。 该标定无超负荷能力。且不能与市电 并网运行。
    此标定的发动机应安装
    在有效电网覆盖区域内
    。备用功率标定的发动 机按平均负荷率为80% 来使用,一年不超过 200小时。在备用功率 点使用时每年不超过25 小时。备用功率标定的 发动机只能在断电时作 为应急电源使用。电网 预先通知的断电不属于 应急电源使用范畴。
    持续功率标定
    可以恒定按100%标定负荷、无时限 连续使用的功率。按此标定的发动 机无超负荷能力。

    二、常用功率标定是可以替代商业电网电 力来使用的功率。常用功率必须按下 列两种类型之一来使用。

    无时限运行常用功率
    按常用功率标定的发动机,可有效 地变负荷无时限使用。在每250小 时的运行周期内,可变负荷的均值
    不能超过所标定常用功率的70%。

    一年内,100%常用功率的整个运 行时间不超过500小时。
    在12小时运行周期内,有1小时有 效超负荷10%的能力。在一年内, 超负荷10%运行的整个时间不超过
    25小时

    限时运行常用功率
    按常用功率标定的发动机,可以无 时限运行于不变负荷用途。诸如使 用功率低而输出功率受限的场合。 在功率决不会超过常用功率标定的 前提下,每年内可与市电并网运行 750小时。但长期高负荷运行将缩 短发动机寿命。一年内并网运行超 过750小时时,请按持续功率标定 运行。

     参考标准: 以ISO-3046为基础的BS-5514和DIN-6271标准。
    环境温度和海拔变化后的修正: 发动机可以在下面的条件下运行,而功率不必进行调整:
    转速为1800r/min的发动机,海拔高度低于1500m (5000ft),环境温度低于40 ℃(104°F)。
    转速为1500r/min的发动机,海拔高度低于1000m (3300ft),环境温度低于40 ℃(104°F)。

    发动机超出上述条件运行,海拔高度高于1525m (5000ft)时,每升高300m (1000ft),功率下调4%;环境温度高于40℃(104°F)时,每升高11℃,功率下调2%
    (升高10°F,下调1%)。


     

    These guidelines have been foumulated to ensure proper application of generator drive engines in A.C. generator set installations. Generator drive engines are not designed for and shall not be used in variable speed D.C. generator set appliacatio 
     
    STANDBY POWER RATING is appliable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. Under no condition is an engine allowed to operate in parallel with the public utility at the
     
    standby Power rating. This rating should
     
    be applied where reliable utility power is available. A standby rated engine should be sized for a maximum of an 80% average load factor and 200 hours of operation per year. This includes less than 25 hours per year at the Standby Power rating. Standby ratings should never be applied except in true emergency power outages.
     
     
     
    CONTINUOUS POWER RATING
     
    Applicable for supplying utility power at a constant 100% load for an unlimited number of hours per year. No overload capability is available for this
     
    PRIME POWER RATING is applicable for supplying electric power in lieu of commercially purchased power. Prime Power applications must be in the form of one of the following two
     
    UNLIMITED TIME RUNNING PRIME
     
    Prime Power is available for an unli- mited number of hours per year in a variable load application. Variable load shouled not exceed a 70% average of period of 250 hours.
     
    The total operating time at 100% Prime Power shall not exceed 500 hours per year.
     
    A 10% overload capablility is available for aperiod of 1 hour within a 12 hour period of operation. Total operating time
     
    LIMITED TIME RUNNING PRIME
     
    Prime Power is available for a limited number of hours in a non-variable load application. It is intended for use in situations where power outages are contracted, such as in utility power curtailment. Engines may be operated in parallel to the public utility up to 750 hours per year at power levels never to exceed the Prime Power rating. The customer should be aware, however, theat the life of any engine will be reduced by this constant high load operation. Any operation exceeding 750 hours


     

     
     
    Reference Standards:
     
    BS-5514 and DIN-6271 standards are based on ISO-3046.
     
    Operation At Elevated Temperatrue And Altitude:
     
    The engine may be operated at:
     
    1800RPM up to 5,000 ft.(1500m) and 104°F (40℃) without power
     
    deration.
     
    1500RPM up to 3,300 ft.(1000m) and 104°F (40℃) without power
     
    deration.
     
    For sustained operation above these conditions, derate by 4% per 1,000ft. (300m), and 1% per 10°F (2% per 11℃).
