PUMPED HYDRO STORAGE

PHS storage
Power plants that use pumped hydro represent the vast majority of the world's energy storage capacity, making it the most extensively used technology in this sector.

Converting electrical energy into gravitational potential energy, the basic premise is simple: when there is an excess of electricity, pumps are used to raise water to a reservoir. When power is required, the water is let out to flow down the turbines again, creating electricity. A water cycle essentially has two reservoirs, one at a higher elevation and one at a lower one, that function as a "charge" and "discharge" mechanism, respectively.

A system generates energy as water flows down turbines during generating (discharging), and it uses electricity to pump (charge) water. With a round-trip efficiency of 70% to 85%, the majority of the energy input is usually recovered by pumped hydro plants. They can store energy for several hours or even days at a time and have extremely enormous capacity, frequently reaching hundreds of megawatts.

Advantages of PHS

Large energy capacity and long duration: Installations of PHS are well-suited for bulk storage since they may produce enormous amounts of energy over long periods of time (typically 6 to 10+ hours), such as tens of GWh in a single site. The result is the ability to redirect massive amounts of renewable energy, such as wind and solar power, from periods of low demand to those of high need.

Grid stability and fast response: In order to handle spikes in demand, pumped hydro facilities can quickly ramp up to full production. They mitigate the effects of renewable power generation fluctuations by providing grid services like frequency management and spinning reserve.

High efficiency and reliability: Due to their sophisticated pump-turbine designs, modern PHS are able to transfer a large portion of their stored potential energy back into electricity, resulting in a high round-trip efficiency of over 80%. Reliability is excellent since the mechanical equipment is strong and well-known.

Longevity and low operational cost: When properly maintained, these facilities can run for 50 to 100 years. Due to their minimal self-discharge and extended lifespan (water can sit for an infinite amount of time), the cost per kWh stored over their lifetime is extremely low. Unlike with batteries, there is no performance loss with age, and maintenance expenses are low.

Mature technology: PHS is the foundation of grid storage around the world and has been for decades. Because of its advanced technology, there is less technical risk and a lot of expertise from engineers when it comes to design and operation.

Standard Borehole Piezometer

This greatly simplifies installation of multiple piezometers in the borehole and also allows the piezometer to be installed with inclinometer casing.

The VW standard borehole piezometer converts water pressure to a frequency signal via a diaphragm, a tensioned steel wire, and an electromagnetic coil. The piezometer is designed so that a change in pressure on the diaphragm causes a change in the tension of the wire. When excited by the electromagnetic coil, the wire vibrates at its natural frequency. The vibration of the wire in the proximity of the coil generates a frequency signal that is transmitted to the readout device. The readout device processes the signal, applies calibration factors, and displays a reading in the required engineering unit.

The VW V-Logger is a compact data logger that monitors one, four, or eight (model-dependent) vibrating wire sensors. It is simple to use and economical to deploy.

The VW V-Logger is ideal for monitoring multilevel piezometers and multipoint extensometers. It is also useful for supplementing a larger, centralized data logging system.

SANLIEN AA222 (TFBA)

AA222 is a tri-axial FBA (Force Balance Accelerometer) with +/-10V voltage outputs. Its dynamic range can be better than 150dB and it is suitable for various applications, such as EEW (Earthquake Early Warning), seismic hazard prevention, as well as RSDH (Rapid Structural Health Diagnostic). AA222 is an easy-to-use, reliable, and robust accelerometer, using IP67 waterproof aluminum alloy enclosure to ensure its performance for all environments.

AA222 provides voltage output and can be used with various brands of recorders; combined with triple technology recorders, it is FA330 integrated seismograph.

The bottom of the AA222 is equipped with a mounting tenon, and an alloy expansion screw is attached randomly, which is easy to install; the shell is equipped with a level bubble meter and level adjustment screws, whether it is wall-mounted or ground-mounted, it can adjust the balance of the body, and can be installed with the current vibration. The surface is closely attached, and the measurement is indeed accurate.
