DESIGN AND DEVELOPMENT OF SPEED MEASUREMENT ARRANGEMENT FOR 200/210 LMZ SETS FOR IMPLEMENTATION OF ELECTRO-HYDRAULIC GOVERNING SYSTEM

摘要

The present invention relates to the development of Speed Measurement Arrangement through which the speed of Steam Turbine Rotor in existing 200/210 MW LMZ set can be accurately measured and converted to electrical signal for feedback to the Electro-Hydraulic Governor. In particular the present invention relates to a method of measuring speed of the turbine meter rotor in electrical form.
