频率调整率
频率调整率是指空载和满载之间频率的差别与满载频率的百分比。

Gateway
A device that acts as an interface between two different communication protocols. The Network Gateway Module (NGM) provides a communication protocol that a PC can understand. Other gateway devices may be used to interface between our Lontalk protocol and other systems such as a SCADA or Building Automation System. Typically, a gateway becomes necessary when a SCADA or BAS does not have a driver developed for Lontalk.
网关
网关是两个不同的通讯协议之间的接口，网关模块（NGM）提供了个人电脑可理解的通讯协议。其他网关设施可能被用作我们的Lontalk 协议和其他系统（如SCADA或楼宇自动化系统）之间的接口装置。当SCADA或楼宇自动化系统没有Lontalk的驱动时，网关就是必不可少的。
Generator
A generator is a machine which converts rotating mechanical energy into electrical energy.

发电机是把（旋转）机械能转化为电能的装置。
Genset Communication Module (GCM)
The GCM provides a communication gateway between the Model 3100 PowerCommand Control (PCCI) and the network. The GCM communicates with the PCCI control over a serial data link. The GCM gets data from the PCCI controls such as voltage, current, engine speed, oil temperature, etc. and then sends it out on the network if another network node is bound to it or requesting data.
机组通讯板
机组通讯板(GCM)是 PCC3100 控制器和网络之间的通讯接口。GCM与PCC通过串行数据连接。GCM从PCC得到如电压、电流、发动机转速、油温等，再把它们发送给需要这些信息的网络节点。
Governor
A governor is a device on the engine which controls fuel to maintain a constant engine speed under various load conditions. The governor must have provision for adjusting speed (generator frequency) and speed droop (no load to full load).
调速器
调速器是安装在发动机上的一个装置，在不同的负载条件下通过控制燃料量来保持发动机的恒定转速。调速器必须具备转速调整（发电机频率）和降速降调整（零负荷到满负荷）功能。
Grid
The utility-owned power distribution system.
电网
电网是指电厂的电力输送系统。
Ground
A ground is a connection, either intentional or accidental, between an electrical circuit and the earth or some conducting body serving in place of the earth.
接地
接地是电路与地渺幡巍怼啤笑桅痞兀地面上的导体的连接，可以是有意的也可以是意外的。
Ground Fault Protection
This function trips (opens) a circuit breaker or sounds an alarm in the event that there is an electrical fault between one or more of the phase conductors and ground (earth). This ground fault protection function may be incorporated into a circuit breaker.
接地故障保护
当一个或多个相导线与地之间出现电气故障时，接地故障保护通过跳脱断路器或报警来示警。这种功能可以一体化设计在断路器上。

Hertz (Hz)
The term Hertz is the preferred designation for cycles per second (CPS) and is used to describe frequency.
赫兹
赫兹是频率单位，也等于周期/秒(CPS)。
Hub
A common connection point for devices or nodes in a network or sub-network. Hubs are commonly used to connect segments of a LAN and contain multiple ports.
分支器
分支器是网络或子网络中设备和接点的集线器，包含很多端口，一般应用于连接局域网的分支。
Hunting
Hunting is a phenomenon that can occur upon load changes in which the frequency or the voltage continues to rise above and fall below the desired value without reaching a steady-state value. It is caused by insufficient damping.
游车
游车是一种在负载变化引起的频率、电压高于或低于期望值，无法达到稳定的现象。它是由于阻尼不足而造成的。

Insulation
Insulation is non-conductive material used to prevent leakage of electric current from a conductor. There are several classes of insulation in use for generator construction, each recognized for a maximum continuous-duty temperature.
绝缘
绝缘体就是非导电材料，用来防止导体中电流的泄露。按最高持续耐热度划分，发电设备中使用的绝缘体有多种等级。

Lagging Power Factor
Lagging power factor in AC circuits (a power factor of less than 1.0) is caused by inductive loads, such as motors and transformers, which cause the current to lag behind the voltage. See Power Factor.
滞后功率因数
交流电路中的滞后功率因数（小于1.0）是由感应负荷引起的，例如发动机、变压器，使电流滞后于电压。（参照功率因数）
Leading Power Factor
Leading power factor in AC circuits (0.0 to -1.0) is caused by capacitive loads or overexcited synchronous motors which cause the current to lead the voltage. See Power Factor.
超前功率因数
交流电路中的超前功率因数(0.0 to -1.0)是由电容负荷或者过励的同步电动机引起的，使电流超前于电压。（参照功率因数）
Line-To-Line Voltage
Line-to-line voltage is the voltage between any two phases of an AC generator.

相电压
在三相四线星形连接的发电机中，相电压是指三相连接点与每相之间的电压。
Load Demand负载需求
Load Demand is a paralleling system operating mode in which the system monitors the total kW output of the generator sets, and controls the number of operating sets as a function of the total load on the system. The purpose of load demand controls is to reduce fuel consumption and limit problems caused by light load operation of reciprocating diesel generator sets.
负载需求是并联系统的一种运行模式，系统监控发电机组总的输出功率，根据系统总负载量决定运行机组的数量。负载需求控制的目的是降低燃料的消耗量，减少往复式柴油发电机组因低负荷造成的故障。
Load Factor
The load factor is the ratio of the average load to the generator set power rating.
负荷系数
负荷系数指的是机组的平均负荷与额定功率之间的比率。
Load Shedding
Load shedding is the process by which the total load on a paralleling system is reduced, on overload of the system bus, so that the most critical loads continue to be provided with reliable electrical service.

在超载的系统母排上，并联系统的总负载被降低的过程称为卸载，以确保最关键负载获得可靠的电力供应。
