A great solution for power plants!
“A leaking HP Bypass valve decreases turbine efficiency, and if it’s unable to stroke due to thermal expansion of the valve internals, turbine damage or unwanted trip events can occur. The HRH Bypass Valve is the heart of the system. Poor control of Reheat pressure due to oscillations caused by pneumatic actuator “stiction”, overshoot or dead time can cause significant fluctuations in IP drum level. Even small changes in temperature or pressure to the steam turbine cause thermal/mechanical fatigue, and can lead to Gas Turbine or safety valve trips.” Click below to learn how REXA was able to provide a repeatable solution for Turbine Bypass Valves! https://lnkd.in/dMyVifE #REXA #Electraulic #Actuation #Accuracy #Reliabilty #Efficency #Innovation #powergen #steamturbine #combinedcycle #power #powerplant #control #turbine #bypass #valve

To save the upfront cost often thermal power plant chose to go with not so suitable technologies. But this leads to a recurring loses which would be way higher than the difference of price for buying the best technology upfront. Think technology before price.🤔🤔

Synchronous condensers and shunt reactors are different devices with distinct functions in an electrical power system. Here are the key differences between synchronous condensers and shunt reactors: 1)- Function: Synchronous condensers are synchronous machines that are operated without a mechanical load. Their primary function is to provide or absorb reactive power to support voltage regulation and power factor correction in an electrical grid. Shunt reactors are devices used for compensating capacitive reactive power in a power system. Their primary function is to consume reactive power to balance the excess capacitive reactance in long transmission lines and cables. 2)- Operation: Synchronous condensers are operated with an over-excited field, allowing them to generate or absorb reactive power based on system requirements. They do not produce real power (active power) but contribute to reactive power balance. Shunt reactors are connected in parallel with the power system and are designed to provide a path for circulating reactive power. They are usually inductive devices. 3)- Voltage Regulation: Synchronous condensers play a crucial role in maintaining voltage levels in a power system. By adjusting the excitation level, they can provide dynamic reactive power support to stabilize voltage during transient conditions. Shunt reactors help to control voltage levels by absorbing excess reactive power, especially in systems with long high-voltage transmission lines where capacitance can lead to overvoltage conditions. 4)- Power Factor Correction: These devices are often used for power factor correction, helping to offset the effects of inductive loads and improve the overall power factor of the system. While shunt reactors are used to control the power factor and mitigate overvoltage issues caused by capacitive reactance. 5)- Installation: Synchronous condensers are typically installed in substations or at key locations in the power grid where reactive power support is needed. Shunt reactors are often installed at substations along transmission lines to compensate for the capacitive reactance introduced by the lines. In summary, synchronous condensers and shunt reactors serve different purposes in power systems. Synchronous condensers focus on dynamic reactive power support and voltage regulation, while shunt reactors are designed to address capacitive reactance issues and control voltage levels in transmission systems. #powergeneration #powerdistribution #condenser #shunt_reactor #transmissionline #powersystem
