发电机组名词（中英对照）

发电机组名词中英对照，在购买发电机组时才能有所了解

有功功率
有功功率（kW），是指发电机组实际供应给负载的功率，它由发电机组的发动机提供，受到发动机马力大小的限制。发热和驱动马达转动靠有功功率完成。
Active Power
Active power is the real power (kW) supplied by the generator set to the electrical load. Active power creates a load on the generator set's engine and is limited by the horsepower of the engine. Active power does the work of heating, turning motor shafts, etc.

后备保护装置
后备保护装置是在其他保护装置动作失败或发生故障时动作的保护装置。
Backup Protection
Backup protection consists of protective devices, which are intended to operate only after other protective devices have failed to operate or detect a fault.

基本负荷
基本负荷是指建筑负荷需求量中不变的那一部分，是构成负荷需求曲线的基数。
Base Load
Base load is that portion of a building load demand which is constant. It is the "base" of the building demand curve.

交流
交流是指电流在正负最大值之间以特定的频率变动，通常频率为50或60赫兹。
AC
Alternating Current (AC) is electric current that alternates between a positive maximum value and a negative maximum value at a characteristic frequency, usually 50 or 60 cycles per second (Hertz).

波特率
串行数据传输速率，约等于每秒钟传输的比特数。比特/秒也可以用BPS表示，kBPS表示千比特/秒。
Baud Rate
The speed of data transmission in serial data communications approximately equal to the number of code elements (bits) per second (BPS). Bits per second are also termed BPS, with the prefix (k) denoting thousands.

差动继电器
作为保护装置，差动继电器由位于系统中两个不同位置的电流互感器提供反馈信息。差动继电器对电流进行比较，如果存在不同则表示受保护区域内有故障存在。这些装置常被用于保护发电机或变压器的线圈。
Differential Relay
A differential relay is a protective device that is fed by current transformers located at two different series points in the electrical system. The differential relay compares the currents and picks up when there is a difference in the two, which signifies a fault in the zone of protection. These devices are typically used to protect windings in generators or transformers.
