    双回线路零序补偿

    双回线零序补偿因子的幅值和相位角使用参数设置“k0m”和“k0mAng”。该补偿仅适用于1区

    以及2、超范围区和反向区。3.5.31.3.2.定向元件(见第4.8.2.4节。)

    每个距离区都有自己的方向测量元件。

    用于测量的电压取决于与参数“UminFault”相关的故障电压。这个

    如果故障电压高于“无故障”和从正常电压导出的电压,以及

    当存储器电压降到以下时使用存储器电压。常规v.t的建议设置为0.1 UN。

    是否无法正确确定方向(参考电压过低或存储器电压衰减),参数“MemDirMode”的设置决定

    保护块或跳闸:块保护块所有区域

    (仅限定向区域)条件。跳闸保护块,除非瞬时和前面的区域方向相反,在在这种情况下保护跳闸。

    3.5.31.3.3.超范围区域

    设置包括名称“4/OR”(“X(4/OR)”…延迟(4和/或)’可用于第四测量区或

    完全独立的超范围区域(但不适用于两个区域同时)通过适当设置参数“延迟(4)或(见第3.5.31.3.5节)。在需要第四个区域的应用中第二个区域用于超范围。

    切换到故障时,需要一个超范围区域,并且区域扩展逻辑和超范围转换跳闸计划。

    3.5.31.3.4.反向区(返回)

    在阻塞方案中使用反向测量区,并且以及用于检测故障能量方向反转的逻辑。它使用参数“X(后)”、“R(后)”和“RR(后)”设置和“RRE(返回)”,其设置范围为0到-300/博士。

    Zero-sequence compensation of double-circuit lines

    The magnitude and phase-angle of the zero-sequence compensation factor for a double-circuit line are set using parameters

    ‘k0m’ and ‘k0mAng’. This compensation only applies to Zones 1

    and 2, the overreaching zone and the reverse zone.

    3.5.31.3.2. Directional element

    (see Section 4.8.2.4.)

    Each distance zone has its own directional measuring element.

    The voltage used for measurement depends on the amplitude of

    the fault voltage in relation to the parameter ‘UminFault’. The

    fault voltage is used, providing it is higher than the setting of

    ‘UminFault’, and a voltage derived from the healthy voltage and

    the memory voltage is used when it falls below. The recommended settings are 0.1 UN for conventional v.t's.

    Should correct determination of direction not be possible

    (reference voltage too low or memory voltage decayed), the setting of the parameter ‘MemDirMode’ determines whether the

    protection blocks or trips:

    Block protection blocks all zones

    (definitive zone only if directional)Cond. trip Protection blocks unless the instantaneous and

    preceding zones are in opposite directions, in

    which case the protection trips.

    3.5.31.3.3. Overreaching zone

    (OR)

    The settings including the designation ‘4/OR’ (‘X (4/OR)’ ... delay

    (4/OR)’) can be used either for a fourth measuring zone or a

    completely independent overreaching zone (but not for both at

    the same time) by appropriately setting the parameter ‘Delay

    (4/OR)’ (see Section 3.5.31.3.5).

    In applications requiring a fourth zone, the measuring unit of the

    second zone is used for overreaching.

    An overreaching zone is necessary for the switch-onto-fault and

    zone extension logics and for overreaching transfer tripping

    schemes.

    3.5.31.3.4. Reverse zone

    (BACK)

    A reverse measuring zone is used in a blocking scheme and

    also the logic for detecting a reversal of fault energy direction. It

    is set using the parameters ‘X (BACK)’, ‘R (BACK)’, ‘RR (BACK)’

    and ‘RRE (BACK)’ which have setting ranges from 0 to -300
