无源系统

According to the different compensating objects, two specific methods of detecting reactive current are put forward.

显然，谐波与无功补偿效果与有源电力滤波系统所采用的电流检测方法有关。

This paper proposes a model for reactive power optimization considering UPFC based on the interior point algorithm .

基于内点优化方法，提出了计及UPFC的无功优化模型，以系统网损最小为目标函数，采用UPFC电压源模型，将其作用等效为一系列电压和功率的约束，直接放到内点法的约束中，在不同的负荷运行方式下进行了优化分析。

The result indicates that velocity of tail water,velocity of air,temperature of air, the roughness of inwall and the length of the tunnel all have effec ...

因此，对水电站空调系统而言，无压尾水洞是一个巨型的天然"空调机"，具有节能、环保和可再生的优点，是一个既节能又节省投资的天然冷源。

"Peerless film system," ASP is running under ASP source can be used for audio-visual entertainment.

The measurement system （called associated with a slowly rotating microphone RRS） is composed of a repeatedly inspirited sound source and the measured result is equivalent to that of using a round microphone array in room acoustics measurement.

室内声学测量中，在声源重复发射声信号的同时，将单个无指向性传声器缓慢而匀速地转动，其测量结果等效于以转盘转轴为中心的圆形传声器阵列，相应的测量系统简称为RRS。
