Siemens has received an order to deliver Statcom reactive power compensation systems for the Power Grid Corporation of India.
Siemens has received an order worth approximately €78 million to deliver Statcom reactive power compensation systems from its SVC Plus series for the Power Grid Corporation of India. Delivery includes planning and engineering services as well as the installation and commissioning of the equipment in four PGCIL substations. The Ranchi, Rourkela, Kishenganj and Jeypore substations are located in the Indian states of Bihar, Jharkhad and Odisha. The Siemens systems will help stabilise the power supply in these areas.
With this static VAr compensator project Siemens is carrying out one of the world’s largest reactive power compensation projects at the 400 kV voltage level. The systems, which are built around an enhanced Statcom (static synchronous compensator), work with a dynamic operating range totalling 2000 MVAr, in addition to 1250 MVAr mechanically switched components. The system has fast response times, which contribute to providing a stable line voltage and frequency.
Siemens builds the core components for the SVC Plus systems in its factory in Goa, India. Reactive power compensation technology is a subset of flexible alternative current transmission systems (FACTS). These systems can regulate the parameters that determine the operation of a power supply grid and account for the quality of transmission. Such parameters include transmission impedances, currents, voltages and phase angles between the different nodes. Reactive power compensation is divided into parallel compensation and serial compensation. Parallel compensation systems, like those to be used in India, primarily regulate the voltage at the connecting point and thus facilitate a stable, reliable grid operation.
This order is not the first one that Siemens has received in the area of flexible alternating current transmission systems in India – it has been delivering fixed series capacitors (FSC) to the Power Grid Corporation of India on a regular basis since 2003. The first thyristor controlled series capacitor (TCSC) was delivered to PGCIL in 2004.
