1. | The development of an ATDS should be realized individually for each operating station with consideration of the design characteristics of the units and should be aimed at solving one of the most important problems of increasing the operating reliability of the main equipment and economy of operating the hydrostation. |
2. | The deterministic approach to compiling technological diagnostic algorithms makes it possible to use the operating experience gained and to make the diagnosis on the basis of the actual technical state of the units of the hydrostation. |
3. | The ATDSs should satisfy the requirements of prompt, integrated, automatic, and dynamic performance (possibility of the modular buildup of problems being solved as a result of developing new diagnostic means and methods). |
4. | The proposed development of an ATDS at the unit level should be done with the possible prospects of inclusion in the PCS of the hydrostation. |

我国水电机组国际招标采购除为了获得技术先进、制造质量好、运行可靠的设备外,还兼顾着引进技术,提高国内制造能力和水平的目的。为此,国内制造厂必须参与与供货合作生产。国内外制造厂对设备生产任务份额的竖向、横向、斜向分割模式各有利弊。通过鲁布革等工程的实践,可以了解在不同资金来源的情况下,如何促进国内外厂商联合。 相似文献
