Generator & Transformer Protection System In power plants, equipment protection and maintenance is of particular importance, in addition to capital saving, protection system plays an important role in reliable electricity generation. In case a machine lacks the adequate safety mechanisms, or the protection system is somehow out of service, most likely, in the event of […]

Comprehensive Electrical, Control and Protection Systems for Solar Farms Given the global community’s strong emphasis on sustainable development and the preservation of the environment for future generations, there is an urgent need to prioritize the development and utilization of renewable energy sources. MAPNA Group, a leading company in the power industry, has made significant strides

شرح کلی سیستم: توربین بادی ۲۵۰۰ kW مبتنی بر DFIG (Doubly Fed Induction Generator) مپنا، یک توربین بادی ۲.۵ مگاواتی بوده که برای عملکرد تحت بادهای ملایم (Class II IEC) طراحی شده است. این توربین دارای سطح جاروب روتور که ۹,۱۵۶ متر مربع است؛ این توربین به ویژه در رژیم‌های بادی متعادل و نیز پایین،

شرح کلی سیستم: سیستم حفاظت زمین از آنجایی که شبکه انتقال نیرو سه سیمه است، با درنظر گرفتن آنکه طرف ثانویه ترانسفورماتورهای قدرت اتصال مثلث می‌باشد، بنابراین در صورت بروز اتصالی فاز به زمین، مسیر برگشت جریان به شبکه را نخواهد داشت و اشکال شبکه آشکار نخواهد شد و لذا لازم است که برای چنین

شرح کلی سیستم: Generator start-up system or Static Frequency Converter (SFC) has long been integrated into MECO products. MECO has recently developed its domestically-produced system called MAPLCI.   SFC Advantages Reducing equipment and system complexity Allowing unlimited generation of varying frequencies Significantly reducing maintenance costs Increasing accuracy in supplying varying frequencies General system description: In

Generator Excitation System The THYRIPOL 520/1800 R excitation system is one of the main strategic systems in power plants used in gas and steam units. It is manufactured by MECO under SIEMENS license for medium and large-scale generators.  To achieve redundancy (2×100%) and increase the system reliability, two separate working channels including two AVR controllers

Generator & Transformer Protection System and Synchronization System In power plants, equipment protection and maintenance is of particular importance, in addition to capital saving, protection system plays an important role in reliable electricity generation.

Boiler & Burner Control & Protection Systems The automatic control system for the boiler in the combined cycle power plant has the following control loops for steam boiler protection. Boiler start-up: The local panel handles the basic operations such as turning on or off the boiler, and operating and managing pumps, fans, valves, etc.  The

Distributed Control System (DCS) MECO provides various solutions for automation and control of different processes in industrial sites, especially power plants and oil and gas sites. These solutions include systems under SPPAT2000-3000 license and domestically-manufactured MAPCS distributed control system. A distributed control system in large industrial sites consists of the following components: Instruments/actuators are the

Gas & Steam Turbine Governor Control System Turbines can be classified into two types based on their power source: gas and steam. In a gas turbine, gas combustion at high pressure and temperature creates the driving force to rotate the blades. In a steam turbine, superheated water vapor at high temperature and pressure spins the
