Invensys Process Systems (IPS) has signed five contracts to make automation upgrades to five power plants on behalf of Perusahaan Listrik Negara, Indonesia’s largest electricity producer. Under the terms of the agreement, IPS will provide distributed control systems (DCS) and automation solutions to power plants located in Banten, Jawa Barat, Jawa Tengah and Jawa Timur, representing some 3820MW of power generation capacity. The automation upgrades at PLN Persero plants are part of a larger effort by the Indonesian government to expand the country’s power generation capacity. The DCS contract encompasses the installation of an advanced IPS I/A Series automation infrastructure, integrating more than 30,000 I/O points. The systems will be used to control the new plants’ boilers, turbines and generators, utilizing IPS’ Performance Plus coordinated control system technology, well-proven in power plants worldwide. Subsystem applications will include data acquisition systems, furnace safety supervisory systems, boiler and turbine sequence control systems, turbine digital electro-hydraulic control systems, feed water pump mechanical electro-hydraulic control systems, electric control systems, and balance of plant systems.
