Control and Instrumentation Digital Control and Communication Systems Development of Modern Control Strategies for Gas Turbogenerators Type 5001, in an Industrial Controller The development and factory testing of the Digital Control System for the Turbo gas Units 5001 (SCD-UT 5001) in an industrial platform was concluded, including the software for the speed and power fuzzy controllers. The studies undertaken in this project generated the required knowhow for technology development, as well as for its implementation in actual gas turbine controls to improve the profitable operation of these machines. The implantation of the SCD-UT 5001 in an industrial platform makes the commercialization of this product feasible in the short term. Separation Header Flow Measurement and Monitoring at the Mora Battery Complex A real-time measurement and monitoring system was developed to improve the conventional well production measuring procedure used by Pemex. The precision, reliability and repeatability of the gas flow measurement comply with the American Gas Association standards, and those of liquid flow comply with the American Petroleum Institute standards. The commissioning of the Real Time Measurement and Monitoring System will allow Pemex to optimize its production, schedule maintenance, evaluate the wells residual life and schedule their production, as well as to anticipate possible contingencies. Following the evaluation of results of this system, Pemex might install similar systems in other Battery complexes throughout the country. Electric Variables Recorder for Distribution Lines (RVE-23) The RVE-23 electronic device was developed to measure Ampere-hour when applied in the detection of illegal power consumption and for calculations of energy balance and quality. This product may provide financial 2

savings for the power utilities, and an opportunity for IIE to transfer its technology to the industry. Technical Assistance for the Analysis and Emission of Corporate Policies and Technical Specifications of SISPA, and the Specification and Installation of CIAME in Pemex The Subsystem of Industrial Safety and Environmental Protection (Subsistema de Información de Seguridad Industrial y Protección Ambiental, SISPA) was developed and put into service at Pemex industrial plants, and the Institutional Center of Emergency Attention and Administration (Centro Institucional de Atención y Manejo de Emergencias, CIAME) was implemented at the Pemex Administrative Center in Mexico City. With these systems, Pemex will efficiently supervise, attend and coordinate all necessary actions to mitigate the impact of incidents and/or accidents, which might occur in any of its industrial plants. Also, the number of industrial safety and environmental protection reports and their content will be optimized; minimizing the delivery time to the required destinations. In addition, the performance indices linking the efficiency of the actions to the established goals at the work centers will be calculated. Information Technology Support for the Office of Technology and Professional Development (Subdirección de Tecnología y Desarrollo Profesional, STDP) at PEP A prototype was built to evaluate knowledge administration technologies. A virtual university was integrated into the STDP Intranet, for accessing didactic material on demand and managing courses, students and instructors. Support was provided to specify hardware and software for STDP procurement, which already has an operative infrastructure that supports critical technologies, groups of specialists, and multidisciplinary projects. Support was also provided to users in Mexico City and Villahermosa, Tabasco; the information infrastructure was maintained and videos were prepared for Web transmission. 3 Instituto Instituto de Investigaciones de Eléctricas Eléctricas 3

Simulation Development of Simulators for Operator Training and Equipment Testing Upgrade of the Computer Equipment Platform for Simulator I The Simulator I was delivered and ready for training in CFE s Operator Training Center in Ixtapantongo (Centro de Adiestramiento de Ope radores de Ixtapantongo, CAOI) in 1984. The computer equipment was a set of two SEL mini-computers series 32/77, linked by a shared memory. CAOI asked IIE to update the Simulator I computer equipment. The new equipment consists of a network of workstations, using the same hardware architecture and simulation environment as Laguna Verde s new simulator platform. The benefits that CAOI obtained by replacing the Simulator s platform included the ability to select operating scenarios, utilization of standard software systems, guaranteed maintenance and spare part service according to the conditions provided by each manufacturer. Also, the peripheral equipment is based on standards that will assure the compatibility of future components with the computer equipment and, with that, a simpler and quicker preventive maintenance, which represents savings. Simulator for Training of Combined Cycle Plant Operators Based on the Unit 1 of the Samalayuca II Combined Cycle Plant, Using a Commercial Development Platform The simulator for the training of combined cycle plant operators was based on the document "Technical Specifications for the Design, Construction, Installation and Start-up of a Simulator with the Samalayuca II Combined Cycle Power Plant Unit 1 as a Reference Plant", sent by CAOI. The results of this project include the development of a full-scale simulator that reproduces the behavior of the Unit 1 of the Combined Cycle Plant in its entire operation range, according to the scope offered by the ProTRAX v 6.1 package. The results also include the simulator s documentation, model specification, and the computer equipment and software licenses required for simulator operation. 4 Instituto de de Investigaciones Eléctricas 4

Information Systems Advanced Information Technology Specialized Technical Assistance in the Implementation of the SAP R/3 System in CFE IIE s Information Systems Area (Gerencia de Sistemas Informáticos, GSI) continued with the project entitled Automation of Administrative Solutions in Real Time (Automatización de Soluciones Administrativos en Tiempo Real, Asare) for the General Office of CFE, through the implementation of the SAP R/3 system in its regions. The design, development, revision, correction and tests of the Sapscript formularies were carried out. The necessary workflow structures were created for the startup in CFE s Occidental and Central Production Regional Areas, and support was provided to the users of the different CFE regions. Information System for the Calculation of the Outage Time Per User at LyFC (Luz y Fuerza del Centro) Requirement Specifications of the Telecommunications Administration System of CFE s Area of Information Technology and Telecommunications (GIT) GSI developed the technical specifications for the Telecommunications Administration System (Sistema de Administración de las Telecomunicaciones, Satel) and a prototype for the administration of frequencies and payments to the Secretary of Communica-tions and Transportation (Secretaría de Comunicaciones y Transportes, SCT) for CFE. The development of the Information System for the Calculation of Outage Time per User (Sistema de Información para el Cálculo del Tiempo de Interrupción por Usuario, SICTIU) included the design phases of the database, and the development of the interface and information modules. These products were installed in LyFC s server and client terminals. Functional testing was performed and the staff was trained in the use of SICTIU, as well as in the use of the development tools. A client/server architecture system with a centralized database was developed, with user friendly interfaces for capture and consulting of the outages from the Mexico City offices. 5
