求翻译：但它要求调度中心必须有因地制宜的电压和无功优化实时控制软件，而且对各变电所通道的可靠性要求高，另外，在各变电所要具有智能执行单元。但在我国目前各变电所的基础自动化水平层次不一的情况下，实现全系统的集中优化控制有较大的难度，多数是按照丰枯期制定电压、无功控制计划，交厂方人员调试，调度人员根据运行情况作临时调整。是什么意思？

But it requires dispatch centers must have local conditions of voltage and reactive power optimization in real-time control software , and reliability requirements of each substation channel is high, in addition , at each substation to have intelligent execution units.

However, it requires that dispatch center must have a local voltage and reactive optimized real-time control software, but also for the substation channel reliability requirements, in addition to the substation to a Smart Implementation Unit. However, in my country, which is currently the Substation

But it requests the voltage and the idle work which the control center must have acts as circumstances permit optimizes the real-time control software, moreover requests high to various transformer substations channel reliability, moreover, must have the intelligent execution unit in various transfo

But it requires scheduling centers must have local voltage and reactive-power optimization of real-time control software, and high reliability of the substation in the channel, in addition, in each substation intelligent execution units. But in our current context of substation based on varying leve
