While renewable energy has been introduced as a measure against global warming, demand for stabilization control of power systems is increasing.
Our pumped-storage power generation system not only
ensures peak shaving, but also provides systems that contribute to power grid stabilization control, including the variable-speed pumping technology
*1.
Overview
We provide function-intensive integrated cubicles as control devices for many small hydro-electric power stations*2 throughout Japan.
Since the scale of power generation is relatively small, a lineup of function-intensive standard control cubicles that do not occupy the installation location is available and unattended operation by remote monitoring control is possible.
Function-intensive control system
Hitachi has provided a variety of generator excitation systems for thermal, hydro-electric and nuclear power plants for decades.
Hitachi provides optimal systems according to customer specification from small to large capacity generator.
AVR : Automatic Voltage Regulator
HMI : Human Machine Interface
G-HIACS system basically provides plant information to monitoring screens in central control room. It collects a wide variety of plant-related information in real time serving as an HMI (Human-Machine Interface) ,saving labor and supporting appropriate judgement by operators. The system has high reliability and expandability utilizing industrial computers.
