因此，利用计算机实时监控发电机机组的运行状态，准确地读取各个参量，并能根据需要远程控制发电机是势在必行。 - Power station simulation system has two main parts : part one is the generator sets ? he diesel engine , the generator and accessories . part two includes monitoring , protection , alarm , operation devices as well as devices that regulate the operation of the generator
仿真电站设备可分为两大部分：一是发电机组，即柴油机、发电机及其附属设备；二是监视、保护、报警、操作和控制发电机运行的设备。 - In this paper , several scheme of vscf is compared firstly , of which gets doubly - fed generating mode . doubly - fed vscf wind power generating system uses a doubly - fed induction generator , which rotate speed can be able to change with wind turbine , and it ensures a constant - frequency output , by controlling the frequency of current input into rotor windings . in vector trans control system , the control of stator active power and the control of stator reactive power can be essentially decoupled , and the former is via torque component and the latter is via exciting component of stator current
本文首先比较了几种变速恒频方案，从中选择了双馈式变速恒频方案；它运用双馈电机的工作原理，允许发电机转速变化，而在电机转子侧接入低频励磁电流，通过控制该电流的频率，保证双馈电机定子输出的频率恒定；再结合矢量控制技术，通过调节转子电流来控制定子电流的转矩分量和励磁分量，相应独立地控制发电机输出的有功功率和无功功率。 - The stator of aceg is connected to the grid and the three symmetrical excitation windings in the rotor are fed by converter . the magnitude and frequency and phase and phase sequence of excitation voltage can be controlled , so the magnitude and position of excitation mmf as well as the speed of rotor can be controlled . therefore , acegs have superior performances by contrast with conventional synchronous generators and induction generators , such as upstanding stability , power generation of variable speed constant frequency ( vscf ) , adjusting active power and reactive power independently , and absorbing lag reactive power deeply
交流励磁发电机的基本结构与绕线式异步电机相同，其定子侧接电网，转子上采用三相对称分布的励磁绕组，由变频器提供对称交流电励磁，且励磁电压的幅值大小、频率、相位、相序都可根据要求加以控制，从而可以控制发电机励磁磁场大小、相对于转子的位置和电机的转速，使得交流励磁发电机具有良好的稳定性及转速适应能力、独立的有功与无功调节能力和较强的进相运行能力，性能超越传统同步发电机和感应发电机，因而有着广阔的应用前景。
