Along with the extensive use of power cable lines in power distribution system , the probability of fundamental frequency resonance has greatly increased 随着配电网中电缆线路的大量使用,出现基波电流谐振的可能性大大增加,威胁系统的正常运行。
Each masterpact mw circuit breaker itself conforms to requirement of isolated switch , so save the cost and space of mounting isolated equipment for the power distribution system 每一台mw断路器本身符合隔离开关的要求。为配电系统省去了安装隔离装置的费用和空间。
Aimming at the shortage of load optimal distribution in domestic plant , the paper advances the project of plant online load optimal distribution system which may change the manipulative mode of load from power distribution system to power plant 针对国内电厂负荷优化分配中存在的问题,本文提出了厂级在线负荷优化调度系统的设计方案。
Urban network constitutes the main part of the power distribution system . it is one of the most essential foundations in urban constructions . distribution automation system symbols urban power supply quality level 城市配电网是电力系统的主要构成部分,是城市现代化建设的重要基础设施之一,配电系统自动化标志着城市供用电水平的高低。
The new masterpact mt is completely modularized , intelligentized and easily communicated . it is more secure and reliable . it presents the trend of low - voltage power distribution system 新型masterpactmt空气断路器具有完全模块化、完全智能化、完全通信化的优良性能,代表了低压配电系统的发展方向,全系列从630a - 6300a ,标准交货期为7个工作日。
Low and medium voltage power distribution systems , lighting , ups , afd application , short circuit calculation and protective device coordination , fire alarm systems , telephone systems , hazardous material monitoring and alarm systems 中、低压配电系统,照明, ups ,变频器应用,短路计算,保护装置协调,消防报警系统,电话系统,危险材料监控和报警系统。
Power distribution system does not control unit directly , but delieves instruction of load to plant online load optimal distribution system which shall assure each unit to operate safely , steadily and economically 利用该系统可改变电网中调对电厂负荷控制方式,中调不再直接控制单元机组,而改为对整个电厂发出负荷指令,经优化后,根据分析结果实现各机组的负荷最优分配。
With the development of national economy , power system , which supplies society with important energy , is required to provide better service . as a part of power system , power distribution system play a cache ' s part between power production and power consumption 随着社会经济的发展,对提供重要能源之一的电力系统提出了更高的要求,配电系统作为电力系统中的一个重要组成部分,起着连接电力生产和电力用户方面的纽带作用。
Power distribution system is the most important part of the power system , which orients a lot of users directly , and it is a tie of power supply companies and users . power company statistics show that about 80 % power cut is caused by breakdown of power distribution system 配电系统是电力系统的一个重要组成部分,它直接面向广大用户,是联系供电企业和用户的桥梁和纽带,据电力公司统计,大约80 %的用户停电是由于配电系统故障引起的。
In the experiment of advanced aircraft electrical power distribution system ( aepds ) , terminal built - in test equipment ( tbte ) is one of the most important equipments , which can not only simulate all remote terminal loads " work - states , but also monitor the buses " power quality 为了加快先进飞机配电系统的设计,需要一个既能够仿真系统终端多路负载和汇流条各种工作状态,又能对汇流条进行电能质量监测的实验装置,以便进行地面实验和测试工作。
