21世纪初，全球经济的发展使能源消耗总量创下了又一新高，对电的需求远远超出了对原始能量的需求总和，水利发电，将以其无可比拟的生态和环境优势在将来的能源供应中起重要的作用。就这点来说，自动化系统是水电站水电系统的操作和维护进行优化的一个关键因素。
　　Andritz　AG公司是水利设备先驱制造商之一。120多年来，公司一直致力于水轮机的开发、设计和制造，如今，已成为水电系统的一个全面供应商。“客户们希望仅从一个供应处获取项目执行的所有服务，将接口数量最小化，并且由一个项目经理负责整个项目。” Andritz水利设备部门电气及自动化部经理Armin Martinz作了以上解释。Andritz除了提供Kaplan,Francis, Pelton和小型涡轮机外，还提供完整的电力和过程控制设备。
　　在欧洲，水利发电厂的主要工作集中在更新和维护。相对来说，中国在新建水电厂方面有很大的潜力，而且也会在新系统上投入较大的资金。
　　数字涡轮过程控制系统的开发
　　Andritz过程控制设备其中有一部分是涡轮控制系统，由贝加莱公司设计并开发。贝加莱2005控制器和APROL过程控制系统的良好性能一直得到精湛的演绎。第一个在奥地利使用的系统的两年无故障运行就是最好的证明。
　　在数字涡轮过程控制系统的开发过程中，在供应商方面有很多公司可以选择，因为已经对贝加莱产品有了良好的应用经验，Andritz 理所当然也将贝加莱列入了考虑的名单中。Andritz所需要的供应商除了要能提供适用于水电系统的整套控制产品，还包括过程控制硬件。产品除了要满足诸如模块化，电磁兼容(EMC)等一些基本要求以外，图形化用户界面、可确定性多任务以及简便的远程控制方案也是必要的部分。另外，系统必须兼容C语言源代码，这样，已有的技术才能继续使用，此外，还必须具备自动生成内部文档的功能，来创建详细准确的编程文档。“最主要的要求是用经济的方案完成复杂的控制任务。”Martinz在解释为何选择贝加莱时作如是回答。
　作为Andritz 的2005自动化系列产品的一部分，在ASC 2005控制站中可根据水流系统完成对所有机器及传动装置的自动无人化操作，例如，当水电站储备水量过大时，一旦发生洪水就会造成巨大损失，因此，这时候就要降低水位，保证大水量降临时不会对下游产生灾害性的冲击力。
　　Andritz自动化产品包括：ATC2005涡轮控制系统，机械涡轮和发电机保护，过程控制系统，贝加莱2005自动化系统以及ASC2005，所有这些保证了整个工厂的性能特点能根据实际需要作调整。2005自动化系统维持整个水电厂及上游流水在无干扰时处于正常状态，在干扰发生时也能回复至安全操作状态中。同样来自贝加莱的2005控制系统和APROL过程控制系统针对苛刻的质量要求完成所有的开环和闭环控制任务。
　　我们大多数人都遇到过在暴雨中突然断电的情况，涡轮控制器的作用就是防止这种情况的发生，性能较差的涡轮控制器因其频率不被支持，可能会产生电源不稳，对个人财产带来损失，也对企业管理工厂造成麻烦。同时高昂的维护费用以及随之带来的低劣的控制性能以及长期的不稳定加速了磨损的过程并带来了更多的污染问题。
