Based on the operation status and existing problems of supervision and control system for hydropower plants

the problems such as control system aging

the “neck” of core components

the lack of software and hardware compatibility

and the difficulty of multi-product connection

are studied. Taking the totally-domestic Huaneng Rivival HNICS-H316 computer supervision and control system for hydropower plants as an example

the design and implementation scheme of supervision and control system

which solves the above problems

is introduced. Firstly

a dual ring + dual star hybrid network architecture is taken

Huaneng Rivival FCP100 is adopted in PLC

and the domestic rate of software and hardware of the integrated system is 100%. Then

according to the difficulties in the process of system migration and transformation

the problems of smooth transition between new and old systems

adaptability of totally-domestic control system

excessive controller temperature and so on are solved. Finally

compared with the mature system

the advantages and disadvantages of totally-domestic Huaneng Rivival HNICSH316 computer supervision and control system for hydropower plants are given

and the directional suggestions for improvement and optimization are pointed out. The supervision and control system has been put into operation in large

medium-small hydropower plants

and the operation monitoring indicators are outstanding

which provides a reference for the comprehensive domestic transformation of hydropower supervision and control system.
