Today, electricity producers and suppliers around the world face several challenges:
- Provide reliable energy,
- Generate a growing energy flow
- Deliver energy at a lower cost
- Will meet high energy quality requirements
There are 3 types of devices:
SVC (Static Var Compensator)
A high voltage system that dynamically stabilizes the grid voltage at its coupling point, in order to keep the grid voltage constant at a defined reference value. The main mission: to stabilize the voltage and reactive power control of transmission systems and system nodes or industrial energy distributions.
STATCOM (Static Compensator)
This device is used to compensate the reactive energy in the line, it is connected as a shunt. One of the advantages of STATCOM is to be able to provide a large quantity of reactive power even when the network voltage is low, unlike an SVC28. Its response time is also very low.
MSC / MSCDN or “Mechanically Switched Capacitors”
They are mechanically switched devices. They allow reactive power to be compensated and are more competitive. They are a robust solution for voltage control and grid stabilization under steady state conditions. The MSCDN also offers a damping network to avoid resonant conditions in the electrical system.
