Reason Analysis of Fan Surge during the Load down Process of Generator Unit 机组降负荷过程中风机喘振原因分析
The relation T_w> T_A usually meets the case that water power stations are constructed in long conduit ( without surge tank) form or short conduit and bulb turbine generator. 具有长引水道(无调压井)或短引水道贯流式机组的水电站,往往Tw>Ta。
In the pressure diversion system, the effects of surge tank location on the pressure, on the rotational speed variation of turbine generator set, and on the process of water level fluctuation in surge tank were studied in this paper. 同一引水系统线路,调压室的位置不同,对水击压力,调压室水位波动,机组转速变化会带来多大的影响,这正是本文所研究的问题。
A combined surge generator has been constructed for evaluation of immunity performance of electronic devices, arresters and their non-linear resistance elements under high-energy lightning disturbance. 研制了一台用于评价电子设备、电力设备、避雷器及非线性电阻在雷电干扰下的电磁兼容性能的复合波发生器。
The Study of Phase Tracking for the CWG Surge Generator 组合波发生器中相位跟踪技术的研究
The oscillograph tests the surge waveform of the first order discharge loops of the alternating current arc generator. Nanosecond pulsed waveform is observed in the main surge waveform. 在利用示波器测试交流电弧发生器的一级放电回路的振荡波形时,在主振荡波形中观测到纳秒脉冲振荡波形。
By breaking century old conventions, the conventional generator, the generator surge arresters, the medium-voltage generator breaker and busbars, and the step-up transformer are all replaced by one single component. 它打破了一个世纪以来电厂的传统模式,将常规电厂中的发电机、冲击电压保护器、发电机侧开关、母线和升压变压器全部省略,由一台能量变换器来取代。

When the electric resonance frequency approximatively adds one of the inherent surge frequency of synchronous generator axis. The coupling surge of electric-machine system will occur, the serious accident is the synchronous generator axis will be twist off and the grave economy loss will be result in. 当线路电气谐振频率与同步电机的轴系某一固有振荡频率近似互补于电网工频时,将导致机电系统的耦合振荡,严重时会造成同步发电机大轴的扭断,使电力系统造成重大的经济损失。
