异步自励调频发电机含一个定子绕组和两个转子绕组.分析时可视之为由两个单独的发电机组成:三相异步励磁机和三相异步发电机.前者含定子绕组Ws1，励磁电容Cf，转子绕组Wr1，极对为P1;后者含定子绕组Ws2，转子绕组Wr2，极对为P2(如图1所示).两个转子绕组轴线垂直无磁的铰链，风力发电机，故无互感.经推导有的如下关系.由此可见，发电机，输出电压的频率励磁回路和发电机极对相互关系、转差率和励磁回路的输出频率相互关系.而后者在很大程度上依赖于电容值，故调节电容可调f1.

实验验证:二台型号为YR系列(IP44)的异步电动机，商场发电机，极对分别为P1=2和P2=4，调节电容变动范围为(0.15～1.50)μF.当由高值向低值调节电容.可用转差率数字测试仪[3]测得转差S在0.8～0.2范围内，并可测得f3和f1对应分别在(2～15)Hz以及(15～125)Hz范围内变化.

可见，磁场和转子的旋转速度对输出频率大小的影响***为基本，改变磁场和转子转速可以从基本值降低或升高频率;由频率表达式可以看出，应使p2>p1.因为在这种条件下，励磁回路可在升频以后提高电压和大大降低必须的励磁电容值.这样，异步自励调频发电机不仅可以平稳地调节负荷系统电压的频率，还可以在不改变转子旋向的条件下改变相序.

载流容量

载流容量是以安培数来定义导线安全载流能力。

Ampere

The ampere is a unit of electric current flow. One ampere of current will flow when a potential of one volt is applied across a resistance of one ohm.

安培

安培是电流单位。1伏电压作用于1欧姆的电阻上就会产生1安培的电流。

Annunciator

An annunciator is an accessory device used to give remote indication of the status of an operating component in a system. Annunciators are typically used in applicati*** where the equipment monitored is not located in a portion of the facility that is normally attended. The NFPA has specific requirements for remote annunciators used in some applicati***， such as hospitals.

指示器

指示器作为一个附属装置常用于远程显示系统的各个组成部分的运行状态。指示器通常使用在监测设备不在设备现场的应用。美国国家防火协会对指示器在某些行业的应用有特殊要求，例如医院等。

Apparent Power

Apparent power is the product of current and voltage， expressed as kVA. It is real power (kW) divided by the power factor (PF).

视在功率

视在功率是电流和电压共同作用的产物，用kVA表示。它等于有功功率（kW）除以功率因数。
