把水电站自动控制系统的可靠度与可利用率增加到最大限度是科研开发的首要任务,以便使发电过程优化。可利用率被定义为在一个特定时段确定系统对于某功能状态的概率。它直接依赖于系统的可靠度,或在系统的生命期内,满足应用要求的能力。其中当然也包括规定的限值(即技术数据等)。可靠度是不可避免的故障影响所限制的一个变量。尽管采取各种措施防止出现故障,但仍不会有100%的可靠度。虽然可利用率可通过加强可靠度来增加,但达到理想的可利用率 V=1是不能的。因为系统潜在失效的概率总是存在的。除采取措施提高可靠度外,如果采用多处理器,多通道控制系统、且具有表决功能,仍有可能接近 V=1状态。
To maximize the reliability and availability of automatic control system of hydropower station is the primary task of scientific research and development in order to optimize the power generation process. Availability is defined as the probability that a system will be in the state of a function over a specified period of time. It relies directly on the reliability of the system or its ability to meet application requirements during the life of the system. Which of course also includes the provisions of the limits (that is, technical data, etc.). Reliability is a variable that is limited by the inevitable failure effects. Despite various measures to prevent failure, but still not 100% reliability. Although availability can be increased by increasing reliability, it is not possible to achieve the desired availability of V = 1. Because the probability of potential failure of the system is always there. In addition to taking measures to increase reliability, it is still possible to approach the V = 1 state with multiprocessor, multi-channel control systems and voting capabilities.
