The critical clearing time (CCT) is defined as a given max permissible duration of fault before power system losses its stability.In general,CCT regards fault location,fault type and system structure before and after fault.For a given fault the extent of the CCT is decided on the stable region of the system under the fault.It is indicated from analysis on the transient energy function of the system after reclosing,that the reclosing can decrease the transient energy of the system.If...

The critical clearing time (CCT) is defined as a given max permissible duration of fault before power system losses its stability.In general,CCT regards fault location,fault type and system structure before and after fault.For a given fault the extent of the CCT is decided on the stable region of the system under the fault.It is indicated from analysis on the transient energy function of the system after reclosing,that the reclosing can decrease the transient energy of the system.If the transient energy is decreased to less than that when not reclosing,the reclosing can improve the system`s atability.It is indicated from calculation,for the fault at which the system will loss its stability under the second swing,the reclosing is able to heighten the withstanding capacity of the system to the fault.Comparing with that when not reclosing,the CCT of the fault increases importantly.

临界切除时间(CCT)表示在系统失去稳定前一个给定的故障最大可允许的持续时间。一般认为,CCT与故障地点、故障类型以及故障前后系统的结构有关,对于给定的故障,CCT的大小决定于系统在这种故障下的稳定域,本文通过对重合闸后系统的李亚普诺夫暂态能量函数的分析表明,通过重合闸可以减小系统的暂态能量。如果使得暂态能量减小到比不重合闸时的暂态能量小时,则重合使得系统的稳定性提高了。本文的算例表明,对于在第二摇摆系统失去稳定的故障,通过重合闸可以使系统对故障的承受能力增强,与不重合闸相比,故障的CCT明显增大。

Transmission pricing has become one of the most important problems in many countries where electrical power market is being established. It is necessary to analyze and calculate the electric power flows and losses in one transmission line that induced by different power supplies when power system loss is concerned as a kind of cost of a certain transmission service. A new concept of the separation of electrical power flow is proposed to define the content of the electric power flows or losses in one transmission line that induced by different power supplies in this paper. Using the new concept, It is clear to identify losses of different wheelings without any hypothesis, and these losses satisfy the superposition theorem.

Reactive power compensation is an effective measure to reduce power system loss and improve its efficiency. Based on an analysis of the advantages and disadvantages of reactive power compensation on the outdoor poles used in rural power systems, an automatic compensation measure of detaching the measuring position from the compensation position is proposed. In order to reduce the cost of the reactive power measure device, in the reference of the design idea of the self-supported current sensor and combining it with the technique of applying the SCM and wireless communication technology, a wireless reactive power signal acquiring device is designed. According to the electromagnetic induction principle and electrostatic induction principle, the voltage signal and current signals are received and transmitted by a wireless transmission module after obtaining the power factor value by SCM processing, providing a new method for solving the problem of measuring the reactive parameters of offset lines in the distribution network.

无功补偿是降低电网损耗、提高输配电效率的有效手段。在对当前农电网户外柱上无功补偿的现状分析利弊的基础上,提出了测量点与补偿点相分离的自动补偿方式。为降低无功测量装置的成本,借鉴自给式电流传感器的设计思想,并结合单片机应用技术和无线通信技术设计了无线型无功信号采集器。利用电磁感应原理和静电感应原理取得电流、电压信号,经单片机处理后得到功率因数值,再由无线发射模块传出。从而为解决配电网分支线路无功参数不易测量的问题提供了新的方法。
