signal point indicator 双语例句
Cable. Make use of this principle, we can quickly locate the target cable or break point from large amount of cables, under carpet, the inner of decoration wall and over ceiling1 operation is simple, reliable, the interface is nimble, use is broad, bionic form, carry-over are convenient, since our link tester has two signal output port, it can work when switch is running, this is very convenient. 2 applies to all metal cable such as network cable, tele phone line cable, video cable, automobile circuit. it can not be work with high voltage(above 80V), if you want to locate it, please turn off the cable power supply3 can test the telephone line polarity, connectedness, rough position of breaking point.4 uses the two crocodile clamp to avoid getting rid of the job of make network cable. Use the RJ45/RJ11 interface can connect to the network and the telephone line directly.5 link tester can find out that pair of circuit line cable from large mount of cables. 6 high amplitude ranks 200 times amplification circuit is sui table to locate long distance cable.7 two-sided network lines sequence indicator is easy to examine the network line cable whether or not correctly conveniently. 8 portable types multifunctional bag can encase most of your engineering tools; remit your messy carry-over of implement bothering. 9 adopt two 9V batteries.

Power system Small Signal Voltage Stability Region is a very important part of the small signal stability region, which is a promising tool for preventing against voltage instability and voltage collapse. In this dissertation some aspects of the small signal voltage stability region are studied: 1 An improved local voltage stability indicator named L I is given at first, which can trace the system saddle node bifurcation point accurately regardless of any static load models, such as ZIP and exponential ones. Moreover, L I also has the following additional advantages: the calculation burden of L I is very small even for large-scale systems; the effect of generator excitation limits has been involved in calculating L I. A practical equivalent method for calculating L I is presented, which makes this indicator more practicable; 2 According the indicator L I, a fast method of identifying the system Weak Node Set is presented.
小扰动电压稳定域是小扰动稳定域研究中非常关键的部分，与系统电压失稳和电压崩溃密切相关，本文主要针对实用的电力系统小扰动电压稳定域，做了如下工作：1 提出了一种可准确跟踪系统真正失稳点——鞍节点的改进电压稳定指标 L I ，它求解时不需要积分和对潮流方程的雅可比矩阵求逆，计算速度快，且能计及不同负荷成分和发电机励磁顶值等因素的影响。
