Steam Turbine Lube Oil System Protections Using SCADA & PLCNilesh Jha
Steam Turbine Protection System is designed with today technology to operate the thermal power plants in safe and reliable manner. The protection system operates only when any of the control system set point parameter is exceeded, and the steam turbine will damaged if it continues to operate. This paper presents overview of the steam turbine protection logics of lube of system and implementation for smooth automatic operation by using SIMATIC S7 PLC programming along with monitoring SCADA SYSTEM by using WinCC software.
Demand for high quality, greater efficiency and an automated machine has increased day by day in the industrial sector as well as power plants [1]. Power plants require continuous monitoring and inspection at frequent intervals. There are possibilities of errors at measuring and various stages involved with human workers and also the lack of few features of microcontrollers. Thus this paper takes a sincere attempt to explain the advantages that will be obtained by implementing automation system. The turbine lube oil system control which is the most important part of any power plant, and its automation is the precise effort of this paper. In order to automate a power plant and minimize human intervention, there is a need to develop PLC based system along with monitoring SCADA system that monitors the plant and helps reduce the errors caused by humans [2]. The internal storage of instruction of PLC is used for implementing function to control various types of machines and processes through digital or analog input/output modules.

Following presentation consist of a fundamental steps that took place during a pump overhaul.
this presentation will give you the basic idea about maintenance .
Commonly used maintenance strategies vary from simple ones such as Corrective Maintenance (CM), which is performed upon system failure, to Preventive Maintenance (PM) where maintenance actions are taken at scheduled time intervals. Both strategies, however, have limitations. Recent advances in sensors, control systems, software engineering, and communication technology have prompted manufacturers to move towards the condition monitoring of system health. Maintenance is performed based on the observed system condition, which is referred to as Condition-Based Maintenance (CBM). This presentation gives a comprehensive introduction to CBM, and introduces a method for CBM scheduling for systems with multiple failure modes. It is observed in some applications that the hazard rate corresponding to each failure mode depends on both time and system state. The system state stochastically degrades, and the degradation rate is often a function of time and the degradation level at that particular time. A maintenance alarm is used to signal when the degradation reaches a threshold value. A new joint model is developed for the stochastically dependent time-to-maintenance due to system degradation and time-to-failure of different failure modes. The model is then utilized to obtain the optimum threshold value that maximizes the system’s availability over its life cycle, or, minimizes the long-run cost per unit time. A illustrative example, using real-life data from a reliability test of communication systems, is provided to demonstrate the application of the approach.

Vibration produced by rolling bearings can
be complex and can result from geometrical
imperfections during the manufacturing
process, defects on the rolling surfaces or
geometrical errors in associated components.
Noise and vibration is becoming more critical
in all types of equipment since it is often perceived to be synonymous
with quality and often used for predictive maintenance. In this article
the different sources of bearing vibration are considered along with
some of the characteristic defect frequencies that may be present. Some

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
