control and data acquisition system meaning in English
控制和数据采集系统
Examples
- The supervisory control and data acquisition system ( scada ) is a production course control and attemperment automatization system based on computer
数据采集与监控系统scada是以计算机为基础的生产过程控制与调度自动化系统。 - Standard test method for use in the evaluation of message communications between intelligent electronic devices in an integrated substation protection , control and data acquisition system
用于评价变电所保护控制和数据采集集成系统中智能电子设备之间信息通信的标准试验方法 - 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
仿真结果证明该系统能在各种负荷条件下确保电压合格和无功基本平衡，且能满足变电站对有载调压变压器分接头日调节次数和并联补偿电容器组的日投切次数的限制。通过考虑不同负荷时段对无功功率的需求和负荷突变情况下的控制要求，对上述模糊控制策略进行了改进，仿真结果证明改进后的控制策略能满足不同负荷时段对电压和无功的要求、抑制电压或无功突变情况下的误动作，且有效地减少了有载调压变压器分接头和并联补偿电容器组的调节次数。最后基于变电站scada系统设计了一后台电压无功综合控制软件模块。
