A turbine governor controls the steam flow into turbine system, maintaining the constant speed of rotation irrespective of varying load. Maintaining a constant rotational speed is indispensable for achieving the desired output. Practically, there is a huge variation in load from specified economic load resulting into considerable deviation from the expected performance. Regulating and measuring the speed of machines are primary objectives of governors.
Turbine Governors Assist in the Transformation of Network Frequency
An integral part of turbine arrangement, turbine governors are primarily utilised in the power generation facility. Basically governor is a control component providing advanced protection to the turbines and ensuring safe operations along with an increased productivity and efficiency. Speed of the turbine is also controlled by the governor in the beginning, or at the time of no-load condition, allowing the unit to synchronise with the grid. By controlling turbine load, a governor ensures safe operations of units while running parallel to the grid/generating set.
Currently, steam turbines are utilised across a wide range of applications for mechanical drives and power generation units. Steam turbines generally operate successfully across a broad speed range without depicting failure even at varying loads. Turbine governors protect machines by completely shutting them off or reducing loads in emergency or abnormal situations. Turbine governors also help in changing network frequency, and meeting power generation requirements.
These governors also form an integral part of the hydro-electricity generation systems, enhancing their productivity and efficiency and maintaining the output frequency. Basically regulating the inlet used for rotating turbines for producing electricity, turbine governors obtain the required electricity supply provided with constant speed of rotation. Governor receives the information about current turbine speed and maintains that speed at correct levels by maintaining the inlet.
Government Initiatives are Likely to Propel the Market Growth in the Upcoming Years
The growth of the global turbine governor market is primarily driven by growing demand for electricity from soaring urbanisation and industrialisation, according to report by Future Market Insights (FMI). Many power generating facilities are being set up owing to rising demand for electricity from the end-use sectors. In addition, major steps are being taken for increasing the efficiency and capacity of existing facilities. These factors are expected to fuel demand for turbine governors in the near future.
In contrast, lower rate of replacement of turbine governors is likely to restrain the market growth in the upcoming years. Many initiatives are being taken by the government for increasing the efficiency and productivity of existing facilities. Old prototypes are being replaced with new governors, and turbine governors are being deployed in facilities not having one. These steps are expected to create lucrative opportunities for the global turbine governor market. One of the trends observed in this market is incorporation of turbine governors with sensors for monitoring speed by examination of rotor teeth.
