已經發給你了，這里是個備份。
======================
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.

時常一個微分方程式是根據整合解決的 Fig.3.10 。 整合可能是完成的藉著分析方法或在一部數傳計算機上的數字方法。 整合也可能電子地被一個 op-安培的線路所運行。 的確， op-安培最初為微分方程式的電子的整合發展。
(1) 一個整合之人。 在 Fig.3.11 的 op-安培的線路使用否定回應完成的一個電容器運行整合。
我們有充滿感情的電容器在那回應路徑到一起始 U1 的價值, 然後離開的這一 prebias 電壓在 t=0. 讓我們調查那起始狀態線路在調查什麼將會發生之前在那之後開關是打開。 自從 u 以後+ 大約是零, 因此意志是 u_, 和因此輸出電壓是固定的在 -U1.那輸入對喇叭筒,Ui/R, 的涌流將會流過 U1 電壓來源和進入 op-安培的輸出之內。 如此輸出電壓將會保持在 - U1 直到開關是打開。
在那之後開關是打開在 t=0, 那輸入現在的意志流過電容器和因此 Uc 將會如此是 ( 公式 ) 線路的輸出電壓是 ( 公式 )(3.10) 除為那負號告示, 輸出是那整體 Ui 是依比例決定被我/RC, 可能是製造與任何的相同價值我們希望被適當的選擇 R 和 C。
(2) 剝落而且總計。 我們需要其他二個線路解決類比計算機方法的簡單微分方程式。 剝落提及一個常數的乘法, 像是 K 是哪裡( 公式 ) 一常數。這是喇叭筒的相等, 和因此我們會在 Fig.3.3 使用反轉喇叭筒為那 - 告示或非反轉喇叭筒在 Fig.3.5 為那 + 告示。
夏天農產品那重量總數二或更多 signals.Fig.3.12 表演夏天與二輸入。 我們可能藉由應用相同的推論我們了解線路的操作二手的早了解反轉喇叭筒。 自從 u 以後-=0, 涌流完成的 R1 和 R2 的總數是 ( 公式 )(3.11)
輸出電壓將會經過射頻對平局這涌流調整它本身, 和因此輸出將會如此是那總數 U1 和 U2, 重量被那增益因素、射頻/R 1 和射頻/R 2, 分別地。 如果倒轉是生產在夏天之前是不必要的, 夏天能是跟隨被一反轉, 一有鱗的與一增益 -1. 清楚地, 我們可以把其他的輸入加入平行與 R1 和 R2. 在例子中跟隨, 我們將總數三信號解決一第二次序微分方程式。

超短期負荷預測要用一個不同方法。我們把注意力放在利用近期專觀測到的屬負載模式來推測下一步，而不是圍繞負載、時間、天氣條件以及其他影響負載的因素來建立一個關系模型。超短期負荷預測的解決方法並不多。一些已經發表過的有：一階或二階多項式外推法，自回歸（AR）與自回歸滑動平均模型(ARMA)和人工神經網路。本文介紹了一種解決超短期負荷預測的革命性的新思路，即利用人工神經網路來對負載動態建模。這種方法將神經網路的任務由預測實際負載，變為預測負載的相對增量，從而得到更高的精確度。天數和前一個負載的相對增量作為輸入變數。當預測出的實際負載作為輸入變數時，提演算法比（剛提到的）這個方法更強大。當用訓練數據代表整串可能的負載和當前天氣狀況是，表現為低靈敏度。當當前天氣狀況與應用於數據挖掘的天氣狀況不同時，本方法的優越性尤為明顯。（因為）這種情況下，基於傳統的數據網路的預測可能產生錯誤預報。在第十一節，將對本方法作詳細講解。此法已經在美國一家電力企業的在線負載預報上應用，並取得成功。第111節將具體講解這次次應用，並提供一些由此得出的關於精確度的資料。

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
