Rotork intelligent electric valve actuation with digital 2-wire monitoring and control has been specified for valve automation at the Olivenza Thermosolar power plant in Spain, a CSP (Concentrated Solar Power) technology facility generating eco-friendly electricity for up to 50,000 households.
More than 100 IQ actuators and two Pakscan P3 hot-standby master stations have been supplied, fully installed, cabled and commissioning by Rotork Iberia. Rotork’s intelligent IQ actuator technology is recognised for isolating and regulating valve duties in the field of power generation. The use of solid-state electronics as an alternative to switch mechanisms and counter limiting devices, combined with programmable micro-processor based control and instrumentation functionality, offers many proven benefits.
These include ‘non-intrusive’ configuration and data transfer by means of a hand held instrument via a secure, bi-directional link. This system is used to perform all the switch setting and commissioning functions that were traditionally only achieved by removing electrical covers. Using the multi-lingual menu on the actuator display screen, it is quick and easy to commission the valve, with or without mains power connected.
The same instrument is used to download this data and upload it to other IQ actuators with similar commissioning parameters, simplifying and speeding up the operation, or to download actuator operating information from the actuator’s data logger. The inclusion of a data logger enables an event-by-event history of valve activity to be generated, including torque profiles produced during each opening and closing. Using Rotork’s IQ-Insight2 software, these can be compared with the valve torque signature profile logged during the commissioning process to identify the trend of valve operating wear or isolate tight spots and other problems. Analysis of this data improves asset management through fault diagnostics and preventative maintenance.
Digital two-wire control is provided by Rotork’s proprietary Pakscan P3 system, the third generation of a market-leading product, capable of monitoring and controlling up to 240 field units without repeaters on a single highway with a length of up to 20 kilometres. Designed specifically for the valve actuation environment, Pakscan combines high reliability and efficiency with low maintenance costs. In providing the vital link between the actuators in the field and the centralised supervisory control room, Pakscan incorporates secure field communications with inbuilt network redundancy to maintain control even in the event of equipment or cable failure.
The Olivenza Thermosolar power plant is the second plant to be operated by the Spanish company Ibereolica.

The AWK-6222 outdoor wireless AP/bridge/client avoids interruptions in WLAN transmissions with its dual 2.4/5 GHz RF modules, which allow two independent wireless connections over different frequencies. To maximize wireless and wired network availability, the AWK-6222 can incorporate Ethernet redundancy using RSTP, and power redundancy using dual DC power inputs and PoE. In addition, the AWK-6222 is housed in an IP68 metal casing with M12 connectors for total protection against dust, water, vibration, and other environmental effects. This rugged unit supports seamless roaming to achieve ultrareliable and redundant wireless networks under challenging outdoor, mobile conditions. These industrially hardened features let you set up a rock-solid WLAN to ensure that your entire network will always be in service. The AWK-6222 is compliant with the essential sections of EN 50155, covering operating temperature, power input voltage, surge, ESD and vibration.
