A. BHEL – an overview
BHEL is the largest engineering and manufacturing enterprise in India in the energy related infrastructure sector today. BHEL was established more than 40 years ago when its first plant was setup in Bhopal ushering in the indigenous Heavy Electrical Equipment Industry in India a dream which has been more than realized with a well recognized track record of performance it has been earning profits continuously since 1971-72.
BHEL caters to core sectors of the Indian Economy viz., Power Generation's & Transmission, Industry, Transportation, Telecommunication, Renewable Energy, Defense, etc. The wide network of BHEL's 14 manufacturing division, four power Sector regional centres, over 150 project sites, eight service centres and 18 regional offices, enables the Company to promptly serve its customers and provide them with suitable products, systems and services – efficiently and at competitive prices. BHEL has already attained ISO 9000 certification for quality management, and ISO 14001 certification for environment management.
POWER GENERATION
Power generation sector comprises thermal, gas, hydro and nuclear power plant business as of 31.03.2001, BHEL supplied sets account for nearly 64737 MW or 65% of the total installed capacity of 99,146 MW in the country, as against nil till 1969-70.
BHEL has proven turnkey capabilities for executing power projects from concept to commissioning, it possesses the technology and capability to produce thermal sets with super critical parameters up to 1000 MW unit rating and gas turbine generator sets of up to 240 MW unit rating. Co-generation and combined-cycle plants have been introduced to achieve higher plant efficiencies. to make efficient use of the high-ash-content coal available in India, BHEL supplies circulating fluidized bed combustion boilers to both thermal and combined cycle power plants.
The company manufactures 235 MW nuclear turbine generator sets and has commenced production of 500 MW nuclear turbine generator sets.
Custom made hydro sets of Francis, Pelton and Kapian types for different head discharge combination are also engineering and manufactured by BHEL.
In all, orders for more than 700 utility sets of thermal, hydro, gas and nuclear have been placed on the Company as on date. The power plant equipment manufactured by BHEL is based on contemporary technology comparable to the best in the world and is also internationally competitive.
The Company has proven expertise in Plant Performance Improvement through renovation modernisation and uprating of a variety of power plant equipment besides specialised know how of residual life assessment, health diagnostics and life extension of plants.
POWER TRANSMISSION & DISTRIBUTION (T & D)
BHEL offer wide ranging products and systems for T & D applications. Products manufactured include power transformers, instrument transformers, dry type transformers, series – and stunt reactor, capacitor tanks, vacuum – and SF circuit breakers gas insulated switch gears and insulators.
A strong engineering base enables the Company to undertake turnkey delivery of electric substances up to 400 kV level series compensation systems (for increasing power transfer capacity of transmission lines and improving system stability and voltage regulation), shunt compensation systems (for power factor and voltage improvement) and HVDC systems (for economic transfer of bulk power). BHEL has indigenously developed the state-of-the-art controlled shunt reactor (for reactive power management on long transmission lines). Presently a 400 kV Facts (Flexible AC Transmission System) project under execution.
