電網(wǎng)諧波異地并聯(lián)補償?shù)难芯?/li> - Abstract : this paper analyses principles for power frequency inductive furnace and power factor parallel compensation and three phases balance , deals with processes of power factor compensation and three phases balance for plc automatic power inductive furnace . for saving source and shortening time of smelting and improving electrice net , they will be of great significance
文摘:分析了工頻感應(yīng)爐的工作原理、功率因數(shù)并聯(lián)補償原理和三相平衡原理.論述了plc自動控制工頻爐的功率因數(shù)補償、三相平衡的過程.它對節(jié)省能源，縮短熔煉時間，改善電網(wǎng)功率因數(shù)有重要意義 - 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
仿真結(jié)果證明該系統(tǒng)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(diào)壓變壓器分接頭日調(diào)節(jié)次數(shù)和并聯(lián)補償電容器組的日投切次數(shù)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，仿真結(jié)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(diào)壓變壓器分接頭和并聯(lián)補償電容器組的調(diào)節(jié)次數(shù)。最后基于變電站scada系統(tǒng)設(shè)計了一后臺電壓無功綜合控制軟件模塊。 - It's difficult to find parallel compensation in a sentence. 用parallel compensation造句挺難的
