In this way, the precision and the real time of calculation of the aberrance will influence the effect of the compensation. However, it is puzzle to calculate aberrance of instantaneous voltage and current on power net in real time.

这种模式下，畸变量的实时检测是一个问题，特别是对于事先未知扰动量的电网来说，无延时地检测计算出畸变量是一个难以解决的问题。

However, the distribution of elements' absorbing power fails to show the continuity of energy flow in electric networks.

电路理论中的功率是基于电场力对电荷做功的元件吸收功率，它在电网中的分布不能展现能量流动的连续性。

By building the low frequency model of the system, in the rectifying mode and regenerating mode, the dynamic adjusting procedure of realization for unity power factor, absorbing or regenerating capacitive reactive power, inductive reactive power from or to power grid are investigated.

通过建立系统低频数学模型，分别在顺变和逆变状态下，探讨系统实现单位功率因数、从电网吸收或回馈容性、感性无功功率的动态调节过程。

In addition, there was some difference in cycle between self – generating sine signal and the actual electrical network, so the great accumulated error and non synchronous error will be presented after several cycles.

另外，由于在传统的傅立叶系数数值求解时，微处理器进行离散化，所用的内部产生的正弦信号周期不能与实际电网周期完全相等，因此在多个电周期后，会有较大的积累误差和非同步误差。

At present this system is applying in national network and affiliated company.

目前该系统已经在国家电网公司及其下属公司应用。

The applications of inverter aggravate the harmonic pollution of power system.

变频器的大量应用，加重了电网的谐波污染。

For ensure safety normal use upmentioned equipment, then had to eliminate existent all sorts ofs disturbance in electrified wire netting, such as press, wave gush, depression, sinkness, aiguille disturb and so on … Base on above concept, our company de engineer Men cumulate ten number year current supply device de designer manufacture experience, very adopt sines energys dispensers circuit and our companys specific high-tech, launch this new generation de purify AC power certain press utensil.

为了保证安全正常的使用上述设备，就必须消除电网中所存在的各种干扰，诸如过压，波涌，低压，下陷，尖峰干扰等等…基於以上理念，本公司的工程师们累积了十数年电源设备的设计制造经验，特采用正弦能量分配器电路及本公司特有的高新技术，推出此新一代的净化交流电源稳压器。

Our power grids, air and ground transportation, telecommunications, and water-filtration systems are in jeopardy as well.

我们的电网、空中和地面交通、远程通讯和水过滤系统也处于危险之中。

Technophiles imagine a time when smart grids will seamlessly balance supply and demand for power by turning down millions of air-conditioners a notch when the wind drops or the sun goes behind a cloud.

高科技人士描绘了一个新时代到来，那时智能电网可以连贯地平衡电能的供求关系，在风力下降或太阳处在云彩背后的情况下电网会自动降低数百万空调一个等级。

The primary frequencyregulation has direct effect on the grid frequency, and it is very important to maintain thestability of power systems.

一次调节直接影响电网的频率质量，对电网的稳定起着重要的作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
