| Abstract: | Considering the versatility and complexity of on-line vibration monitoring of hydroelectric generating sets, with design ideas concerning sensing, transmission, computer application technology and modularization, a way of vibration monitoring with fictive instruments is proposed in the paper, in which sensor selection and installation, data acquisition, transmission, treatment are studied and analyzed. Compared with conventional vibration monitoring systems, systems developed with fictive techniques are featured by facility of operation, easy maintenance, high reliability, completeness of functions, high degree of automation, high flexibility and possibilities of enlargement, with a high performance to cost ratio, remarkably raising monitoring correctness, effectiveness and economy while guaranteeing a safe and highly efficient operation of generating sets.
