  2. There are many plants that have the character of time - varying, large delay, large inertia in the process of production of modern power station such as the superheated steam temperature, the reheated steam temperature, the water treatment of boiler and the load regulation. some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control. it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control, optimal control ， decoupling control and predictive control. and these control systems have large calculation and bad character of real time in general. these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station. now the generator units are developing towards large capacity and high parameters. many new kinds of generating electricity means are coming into being. the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict. the new control means are in bad need to control them effectively

    現代電站的生產過程中存在過熱汽溫、再熱汽溫、鍋爐水處理、負荷調節等許多大遲延、大滯后、特性時變的對象，它們中有些還是具有強非線性特性的對象或多變量耦合系統，採用常規的pid控制手段很難取得良好的控制效果。若應用現代控制理論中的自適應控制、最優控制、解耦控制、預測控制等控制手段，則需要建立被控對象的數學模型，而且往往控制系統的計算量大、實時性差。這些缺點使其很難滿足實際生產過程的需要從而極大地限制了其在現代電站中的應用。
  3. The scale, facility, setup mode and the topper application are increasing, but the network management system still adopts a centralizing structure based on manager / agent model. in the centralizing structure, the network management system can ’ t change with the scale and complexity, which made the system bigger and bigger. all management logic is computing in one workstation, that will occupy too many bandwidth, depress performance and made the workstation become the weakest part, if the workstation overrun or dead, agent can ’ t come back because it must wait manager ’ s command

    目前，我國電信網路正處于高速發展中，網路的規模越來越大，設備種類越來越多，組網方式越來越多樣化，應用越來越復雜，但是網路管理系統仍然普遍採用管理員/代理的集中式管理方法，在集中式網路管理模式中，網管系統不能隨著網路規模和復雜度的變化而變化，致使網管系統越來越龐大;網路管理邏輯全部集中在一個管理工作站中計算，需要佔用大量的帶寬來傳輸設備數據，有效性差，同時管理工作站是系統中最脆弱的部分，一旦管理方超負荷或死機，代理方因為必須等待管理方的指令而無法恢復系統，導致系統崩潰。
  4. We have designed and established data collection center exchange network of sale of the whole company, and realized transfers demand of which met six power supply bureau load management systems by using five frequency point, and succeeded in solving the problem of data collection and control management that main station of power supply bureau provided user terminals

  5. According to the characteristic of nine - area diagram of substation vol / var coordinated control, this system gives the defination of fuzzy sets and the degree of membership of input / output variables, and designs corresponding control rules. the results of simulation demonstrate the system can satisfy the constrains of the day - adjusting times of the switching of on - load transformer and paralleled compensation capacitors, and ensure voltage quality, reactive power basical balance. considering the var requirement in different load time period and the control demand in load saltation, a improved control scheme is provided. the results of simulation show the improved scheme can meet the demand of vol / var in different load time period, protect the wrong operation when either voltage or reactive power appears saltation, and decrease the times of regulation of the switching of on - load transformer and paralleled compensation capacitors finally, a background software module of substation vol / var coordinated control is designed, based on the supervisory control and data acquisition system of substation

    模擬結果證明該系統能在各種負荷條件下確保電壓合格和無功基本平衡，且能滿足變電站對有載調壓變壓器分接頭日調節次數和並聯補償電容器組的日投切次數的限制。通過考慮不同負荷時段對無功功率的需求和負荷突變情況下的控制要求，對上述模糊控制策略進行了改進，模擬結果證明改進后的控制策略能滿足不同負荷時段對電壓和無功的要求、抑制電壓或無功突變情況下的誤動作，且有效地減少了有載調壓變壓器分接頭和並聯補償電容器組的調節次數。最後基於變電站scada系統設計了一后臺電壓無功綜合控制軟體模塊。
