已经发给你了，这里是个备份。
======================
Often a differential equation is Fig.3.10 solved by integration. The integration may be accomplished by analytical methods or by numerical methods on a digital computer. Integration may also be performed electronically with an op-amp circuit. Indeed, op-amps were developed initially for electronic integration of differential equations.
(1) An Integrator. The op-amp circuit in Fig.3.11 uses negative feedback through a capacitor to perform integration.
We have charged the capacitor in the feedback path to an initial value of U1, and then removed this prebias voltage at t=0. Let us examine the initial state of the circuit before investigating what will happen after the switch is opened . Since u+ is approximately zero, so will be u_, and hence the output voltage is fixed at –. The input current to amplifier, Ui/R, will flow through the U1 voltage source and into the output of the op-amp. Thus the output voltage will remain at – U1 until the switch is opened.
After the switch is opened at t=0, the input current will flow through the capacitor and hence the Uc will be ( 公式 ) Thus the output voltage of the circuit is ( 公式 )(3.10) Except for the minus sign, the output is the integral of Ui scaled by I/RC, which may be made equal to any value we wish by proper choice of R and C.
(2) Scaling and Summing. We need two other circuits to solve simple differential equations by analog computer methods. Scaling refers to multiplication by a constant, such as ( 公式 ) where K is a constant. This is the equation of an amplifier, and hence we would use the inverting amplifier in Fig.3.3 for the – sign or the noninverting amplifier in Fig.3.5 for the + sign.
A summer proces the weighted sum of two or more signals.Fig.3.12 shows a summer with two inputs. We may understand the operation of the circuit by applying the same reasoning we used earlier to understand the inverting amplifier. Since u-=0, the sum of the currents through R1 and R2 is ( 公式 )(3.11)
The output voltage will adjust itself to draw this current through RF, and hence the output will thus be the sum of U1 and U2, weighted by the gain factors, RF/R1 and RF/R2 , respectively. If the inversion proced by the summer is unwanted, the summer can be followed by an inverted, a scalier with a gain of – 1. Clearly, we could add other inputs in parallel with R1 and R2. In the example to follow, we shall sum three signals to solve a second order differential equation.

时常一个微分方程式是根据整合解决的 Fig.3.10 。 整合可能是完成的藉着分析方法或在一部数传计算机上的数字方法。 整合也可能电子地被一个 op-安培的线路所运行。 的确， op-安培最初为微分方程式的电子的整合发展。
(1) 一个整合之人。 在 Fig.3.11 的 op-安培的线路使用否定回应完成的一个电容器运行整合。
我们有充满感情的电容器在那回应路径到一起始 U1 的价值, 然后离开的这一 prebias 电压在 t=0. 让我们调查那起始状态线路在调查什么将会发生之前在那之后开关是打开。 自从 u 以后+ 大约是零, 因此意志是 u_, 和因此输出电压是固定的在 -U1.那输入对喇叭筒,Ui/R, 的涌流将会流过 U1 电压来源和进入 op-安培的输出之内。 如此输出电压将会保持在 - U1 直到开关是打开。
在那之后开关是打开在 t=0, 那输入现在的意志流过电容器和因此 Uc 将会如此是 ( 公式 ) 线路的输出电压是 ( 公式 )(3.10) 除为那负号告示, 输出是那整体 Ui 是依比例决定被我/RC, 可能是制造与任何的相同价值我们希望被适当的选择 R 和 C。
(2) 剥落而且总计。 我们需要其他二个线路解决类比计算机方法的简单微分方程式。 剥落提及一个常数的乘法, 像是 K 是哪里( 公式 ) 一常数。这是喇叭筒的相等, 和因此我们会在 Fig.3.3 使用反转喇叭筒为那 - 告示或非反转喇叭筒在 Fig.3.5 为那 + 告示。
夏天农产品那重量总数二或更多 signals.Fig.3.12 表演夏天与二输入。 我们可能藉由应用相同的推论我们了解线路的操作二手的早了解反转喇叭筒。 自从 u 以后-=0, 涌流完成的 R1 和 R2 的总数是 ( 公式 )(3.11)
输出电压将会经过射频对平局这涌流调整它本身, 和因此输出将会如此是那总数 U1 和 U2, 重量被那增益因素、射频/R 1 和射频/R 2, 分别地。 如果倒转是生产在夏天之前是不必要的, 夏天能是跟随被一反转, 一有鳞的与一增益 -1. 清楚地, 我们可以把其他的输入加入平行与 R1 和 R2. 在例子中跟随, 我们将总数三信号解决一第二次序微分方程式。

超短期负荷预测要用一个不同方法。我们把注意力放在利用近期专观测到的属负载模式来推测下一步，而不是围绕负载、时间、天气条件以及其他影响负载的因素来建立一个关系模型。超短期负荷预测的解决方法并不多。一些已经发表过的有：一阶或二阶多项式外推法，自回归（AR）与自回归滑动平均模型(ARMA)和人工神经网络。本文介绍了一种解决超短期负荷预测的革命性的新思路，即利用人工神经网络来对负载动态建模。这种方法将神经网络的任务由预测实际负载，变为预测负载的相对增量，从而得到更高的精确度。天数和前一个负载的相对增量作为输入变量。当预测出的实际负载作为输入变量时，提算法比（刚提到的）这个方法更强大。当用训练数据代表整串可能的负载和当前天气状况是，表现为低灵敏度。当当前天气状况与应用于数据挖掘的天气状况不同时，本方法的优越性尤为明显。（因为）这种情况下，基于传统的数据网络的预测可能产生错误预报。在第十一节，将对本方法作详细讲解。此法已经在美国一家电力企业的在线负载预报上应用，并取得成功。第111节将具体讲解这次次应用，并提供一些由此得出的关于精确度的资料。

From reference 1
In large steam power plants, the thermal energy stored in steam is converted into work by means of turbines. A turbine consists essentially of a shaft or rotor fixed in bearings and enclosed in a cylindrical casing. The rotor is made to turn smoothly by means of jets of steam from nozzles around the periphery of the turbine cylinder. These steam jets strike blades attached to the shaft. Central power stations employ condensing turbines in which the steam passes into a condenser after leaving the turbine. Condensation is effected by the circulation of large quantities of cold water through the tubes of the condenser, thus increasing the expansion ratio of the steam and the consequent efficiency and work output of the turbine. the turbines are connected directly to large electricity generators.
In turbines the action of the steam is kinetic. There is progressive expansion of the steam from the high pressure and relatively small volume at which it enters the turbine to the low pressure and relatively very great volume at which it leaves.
Steam is made by heating water in a boiler. The usual boiler has a furnace in which fuel is burned and the heat given off ring combustion is concted through the metal walls of the boiler to generate steam at a pressure within the boiler vessel .In nuclear plants, steam is generated with the aid of a reator in which the controlled fission of uranium or plutonium supplies the necessary heat for the vaporization of water. Thus the reator replaces the steam generator of conventional plants.
Keywords：, steam

From reference 2
Up until now we have been mainly concerned with minimizing the cost of operating a power system. An overriding factor in the operation of a power system is the desire to maintain system security. System security involves practices designed to keep the system operating when components fail. For example, a generating until may have to be taken off-line because of auxiliary equipment failure. By maintaining proper amounts of spinning reserve, the remaining units on the system can make up the deficit without too low a frequency drop or need to shed any load. Similarly, a transmission line may be damaged by a storm and taken out by automatic relaying. If in committing and dispatching generation proper regard for transmission flows is maintained, the remaining transmission lines can take the increased loading and still remain within limit.
Because the specific times at which initiating events that cause components to fail are unpredictable the system must be operated at all times in such a way that the system will not be left in dangerous condition should any credible initiating event occur. Since power system equipment is designed to be operated within certain limits, most pieces of equipment are protected by automatic devices that can cause equipment to be switched out of the system if these limits are violated. If any event occurs on a system that leaves it operating with limits violated, the event may be followed by a series of further actions that switch other equipment out of service. This is usually referred to as a system blackout.
Keywords：power system, security
From reference 3
System monitoring provides the operators of the power system with pertinent up-to-date information on the conditions on the power system .Generally speaking it is the most important function of the three. From the time that utilities went beyond systems of one unit supplying a group of loads, effective operation of the system required that critical quantities be measured and the values of the measurements be transmitted to a central location. Such systems of measurement and data transmission, called telemetry systems, have evolved to schemes that can monitor voltages, currents, power flows, and the status of circuit breakers switches in every substation in a power system transmission network. In addition, other critical information such as frequency, generator unit outputs and transformer tap positions can also be telemetered. With so much information telemetered simultaneously, no human operator could hope to check all of it in a reasonable time frame. For this reason, digital computers are usually installed in operations control centers to gather the telemetered data, process them, and place them in a data base from which operators can display information on large display monitors. More importantly, the computer can check incoming information against prestored limits and alarm the operators in the event of an overload or out-of-limit voltage.
State estimation is often used in such systems to combine telemetered system data with system models to proce the best estimate (in a statistical)of the current power system conditions or “state”.
Keywords：telemeter, estimate
From reference 4
The main objective of proction control in power system is to minimize the cost of generated power while maintaining its quality and satisfying the system security constraints. This implies directly that losses in both the generation and the transmission of electrical energy must be as small as possible. All participating generators are run at high efficiencies, the mix of proction resources is exploited economically and the energy is transmitted optimally. Proction control includes general both active and reactive power. However, the main interest in this type of application has so far been focused mainly on the active part. This is the case in this section also. However, interest for the reactive part is rapidly growing and will soon get a great deal of action.
The activities in the proction control field have traditionally been based on planning. This is still the case. The aim is then to break down the overall objective into detailed plans, normally on an hourly basis, that can be carried out by the operator in the control center. Thus, several steps are taken in a hierarchical scheme to support the operator’s ambition always to have proction resources available to meet the load demand and guide him to operate the generating units so that the most economic alternatives are chosen. The security aspects must also be consisted ,e.g. the selection of proction units must not result in line overloads, too high bus voltage etc. If the system suffers the sudden loss of generation, it must be prevented from getting into the alert state for example by activating proction reserves.
Keywords：proction control, security
