What is inertia? And how does it relate to generators and your power systems frequency upon loss of generation. As many of you know inertia is the tendency to remain constant, an object at rest will remain at rest, and a moving object will continue to move unless a force act against it to slow it down. But why does this matter? Well upon the loss of a generator there will now be a load imbalance present in the system and because of this imbalance there will be a change in frequency. How big a change relates to the MW imbalance between load and generation, but how fast the change occurs relates to the system inertia. Upon the loss of generation, a generator will continue spinning for a time, gradually slowing down. A larger inertia results in a slower frequency decay, which gives more time for other generators to increase their output to account for the load imbalance. This is becoming a growing problem in utility systems as more renewables are being placed in-service. These inverter dominated power supplies have lower inertia due to lack of large rotating masses, resulting in a less flexible system. #ElectricalEngineering #Engineering #Utility #Generators #Renewables

Common Uses of Permanent Magnet Generators (PMGs) #permanentmagnet #generator #PMG Permanent Magnet Generators (PMGs) are an essential component in many energy generation systems, harnessing the power of permanent magnets to produce electrical energy. These generators are widely used across various industries due to their efficiency, reliability, and compact design. This article is going to discuss the key applications of PMGs and their impact on modern technologies.

Liquid cooling technology has attracted much attention for its efficient and stable performance, a popular thermal management solution for industrial and commercial energy storage systems Liquid cooling technology is a technology that uses liquid as a heat transfer medium to take away the heat generated by the battery module and circulate the heat. Compared with traditional air cooling technology, liquid cooling technology has higher heat transfer efficiency and cooling capacity, and also helps to increase the energy density of the energy storage system. The liquid cooling system mainly consists of the following parts: 1. Coolant: used to absorb the heat generated by the battery module and carry it to the radiator. 2. Pump: used to drive coolant to circulate in the liquid cooling system. 3. Radiator: used to dissipate the heat carried by the coolant to the outside world to keep the temperature of the battery module stable. 4. Control valve and connecting pipeline: used to control the flow direction and flow rate of coolant, and connect various components. In the design process of a liquid cooling system, the following aspects need to be considered: 1. Selection of coolant: A liquid with high thermal conductivity, stability, and non-volatility should be selected as the coolant. Commonly used coolants include mineral oil, synthetic oil, etc. 2. Pump selection: A pump with high lift, large flow, and low energy consumption should be selected to ensure that the coolant circulates fully in the system. 3. Radiator design: The radiator should have the characteristics of high heat dissipation efficiency, low noise, and corrosion resistance. Common radiators include plate radiators, heat pipe radiators, etc. 4. Design of control valves and connecting pipelines: Control valves and connecting pipelines with stable performance and easy maintenance should be selected to ensure normal operation of the system. Advantages of Nowtech liquid-cooled energy storage systems: 1. Able to effectively control the temperature fluctuation of the battery modules does not exceed 3°C. 2. Enable the battery modules to have a longer cycle life. 3. Ensure the liquid cooling system operates stably, reliably, and is easy to maintain.

#Cogeneration facilities are #power plants where both electricity and steam are produced simultaneously from a single energy source, most often natural gas. #GasTurbines generate #electricity and heat, which can then be used to produce steam. The steam can then be used to generate additional electricity using a steam turbine. Sometimes the waste heat can even have additional uses. This increases a plant’s overall efficiency. ➡ How do #batteries play a critical role in a #CogenFacility? ⬅ 1. Control systems both DC and AC via DC/AC inverter (UPS) 2. #Switchgear operation 3. Activate the gas turbine 4. Flashing the field coil on the generator to start the production of electricity 5. Operating water circulation pumps for cooling 6. Running the emergency DC powered lube oil pump for the gas turbine   Let our experienced and dedicated staff help find your Switchgear battery solutions for any critical application!
