“…Automating a process implies providing added value and competitive advantage, and it is that strengthening technological management in organizations, especially the formulation and development of technological plans, contributes to closing technological gaps between organizations [4], [5]. In this regard, in [6]- [8] they point out that the progress and complexity of new industrial processes have forced productive organizations to seek solutions for the integration of different technologies, such as the use of control systems as well as monitoring systems acquisition, supervision and control (SCADA). By supervising and controlling data remotely and in real time, this system manages to improve the maneuvers of the process [9].…”

<span lang="EN-US">The Chilca 2 thermoelectric power plant, located in the province of Lima, Peru, has an open cycle gas turbine and a combined cycle steam turbine, whose combined capacity is 112.8 MW (Mega Watts). This plant requires auxiliary equipment for its operation, which is why it consists of electrical systems, lubrication system, hydraulic ventilation, pumps, vacuum systems and drainage of condensate generated by the difference in temperature in the steam conductor. Said drainage system is inside a 5-meter-deep basement that, being exposed to the elements, is exposed to falling drops of water that are generated by the vapors that are released due to the difference in temperature, repeatedly flooding and exposing to hazards that affect the normal operation of the thermoelectric plant. The proposed solution is based on the philosophy of a feedback control system, which uses a programmable logic controller (PLC) Siemens 1214AC/DC/Relay programmable logic controller, which, through a frequency inverter, activates the drainage pumps; the frequency range at which the variator works is linked to a 4-position level sensor. The result shows that it was possible to activate the frequency variator in a controlled manner through frequencies of 10 Hz, 30 Hz </span><span lang="EN-US">and 60 Hz, in this way a sustained operation of the drainage system is guaranteed.</span>

“…Referring to a distributed control system implies the generation of relevant data, which goes beyond operational aspects, becoming linked to very useful and important information systems at a strategic level in an organization [13]. With the purpose of supervising, monitoring and acquiring data for decision-making on aspects related to the operation or operation of an industrial process, SCADA systems (Supervisory Control and Data Acquisition) are used [14][15][16][17]. The application of SCADA systems is diverse, however among the processes that use it the most are electricity generation, natural gas, mining deposits, thermal systems, oil pipelines and chemical products dispatch [18][19][20].…”

The objective of this article is to show the application of a supervision, control and acquisition system of an industrial network of chemical products, for which the design of the control logic and the architecture of the industrial network on Profibus-DP protocols is described and Ethernet, with a peripheral terminal station ET-200, through the Siemens CP433 programmable logic controller and level sensor sensors, coupled to radar-type transmitters with an accuracy of ± 0.5 mm. As findings of the implementation of the control system, it was possible to demonstrate the optimal regulation of the filling system of the 3-compartment trucks with a capacity of 300 Kilos each, generating the elimination of spills of the chemical product, as well as the reduction of polluting particles in the work environment. Finally, as a direct consequence, the productivity of the company was improved, which is a relevant aspect at the level of planning, management and direction.

Son zamanlarda hızla artan enerji tüketimi ve enerji kaynaklarının azalması nedeniyle enerjiyi verimli kullanmak önemli hale gelmiştir. Günümüzde arabalar, cep telefonları, ısıtıcı üniteler, akü şarj cihazları, LED sürücüleri gibi elektronik cihazların çoğunun içinde güç dönüştürücüleri bulunmaktadır. Bu çalışmada, çok fazlı senkron düşürücü dönüştürücü devresinin verimini artırmak için bir çalışma yapılmıştır. Devrede birbirine eş dört adet senkron düşürücü dönüştürücü kullanılmıştır. Devrenin kontrolü mikrodenetleyici yardımı ile yapılmıştır. Sabit ve değişken olmak üzere iki çalışma modu için verim değerleri incelenmiştir. Devrede aynı zamanda aktif faz sayısı, anahtarlama frekansı ve yük akımı parametrelerinin değişmesi durumunda verim değerleri tespit edilmiştir. Alınan ölçümlerin değerleri ve çalışma noktaları incelendikten ve her bir yük durumu için optimum çalışma koşulu belirlendikten sonra, kontrol algoritmasına eklenerek değişken yük durumda aktif faz sayısı ve çalışılacak anahtarlama frekansına karar verilmiştir. Böylece devrede ilave eleman kullanmadan ve devre maliyetini arttırmadan devrenin tüm yük koşulları altında maksimum verimde çalışması sağlanmıştır.
