Process Optimization

Combustion optimizer

The task of SILO is to perform an on-line optimization of the current process operating point. The optimizer is implemented above the base control layer in a layered control structure. The SILO system calculates set points or set points corrections for controllers that operate in the base control layer. Control systems of power units in power plants are based on PI (Proportional-Integral) controllers. These controllers control sub-processes (e.g.: oxygen level in exhaust gases or windbox to furnace differential pressure in case of a power unit control system) that have an influence on a main optimized MIMO (Multi Input Multi Output) process (e.g. combustion process in case of a power unit control system).

 

Economic optimization

Billing and reporting is the outlet of the operation of the whole enterprise. It is a single solution that allows to turn raw data from automation systems into invoice items.

This solution allows for maximum simplification of the billing process. Data is imported directly from automation systems, source interfaces, files, or even e-mails, and processpoints are mapped to allow the values to be turned into quantifiable items in the invoices and reports or used for further calculations.

The solution is designed to provide tools for the facilitation of everyday task thanks to solutions such as the following, for instance – time-zones assigned to each project along with a selection of currencies to choose from, contractors and contracts stored within the system with all the necessary information in one place, user groups and profiles allow targeting of issues and access management, tariff calculators can be added to make the billing process quicker and easier.

Microsoft Excel-based templates are used to create simple templates that are then uploaded and saved in the system and can be applied to an infinite number of invoices or reports that belong to the same type. Templates use keywords which, during the generation process, are automatically substituted with relevant values. Tariff calculators and calculations templates are based on the same mechanism, therefore making the process simple and automatic, retaining irrelevant data in the background and providing only meaningful information.

Fully customizable access to each project and each of its modules for each user or user group ensures that each member of the staff can access all the needed functions and won’t have to bother themselves with issues that do not require his or her attention. It is also possible to add Contractors to the Address Book, for their staff to access the data they need, for example project-specific reports or invoices with their company. It ensures that only authorized users will have access to the information that is relevant to them – while also being able to combine inter-project data and calculations for analytical and billing purposes.

GUI is intuitive, user friendly, and offers a wide range of customization without the need of programming or even advanced IT knowledge. The solution is web-based, so it operates via any modern browser without cumbersome installation. Each user logs in using username and password and has full control over project dashboards, which are personalized to display selected data.

Invoices and reports can be exported into PDF or MS Excel files to be processed further. Invoices and reports can be generated automatically, on schedule, or on demand (manually). All generated documents are stored in the system to be downloaded anytime. Log of changes displays changes of status, content, naming, etc. with date, time and username of the user.
