  1. There are two parts in system : one is client and the other is server. with the information increasing, the two - tier construction shows a lot defect. for example, inefficient ; the operating load is unequal to the unwieldy system ; the cost for maintaining the system is high ; the investment in hardware of client is high

    在信息系統中，兩層結構的客戶機服務器模式一度在計算機業內風行，但隨著it技術的發展，大型數據庫的應用系統的出現，這種兩層結構已不能滿足不斷增長的需求，主要體現在以下幾個方面：執行效率無法滿足日益膨脹的客戶數據請求；過于龐大的系統在負載平衡能力上顯得力不從心；系統維護成本偏高，擴充工作量大；客戶端硬體投資比例大。
  2. 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。
