Abstract Information :

Quality assurance of the DAHS is needed. But to what extend?

AMS and DAHS are both required to report emissions to the authorities. AMS has for a long time been quality assured by using certified analysers combined with EN 14181 (Stationary source emissions - Quality assurance of automated measuring systems).
EN 17255 (Stationary source emissions – Data acquisition and handling systems) is a series of four linked standards which describe requirements for the DAHS and the test of this system. After EN 17255-1 and EN 17255-2 has been introduced, a similar approach to EN 14181 is needed in order to extend the quality assurance from the analyser to the DAHS.
EN 17255-3 sets up a performance criteria which can be used by laboratories for testing the DAHS. The criteria ensure that the DAHS is in compliance with the standard. EN 17255-4 is used for on-going quality assurance just like EN 14181 is used for AMS. The two standards are however only a step of the way to quality assure the DAHS.
In this session we will discuss some of the other aspects when quality assuring software systems such as a DAHS system.
We will discuss some of the considerations we had during the development of ReportLoq DAHS.
Discussed subtopics

  • Testing hardware VS software products. Realtime testing vs loading of large data sets.
  • Software lifecycle requirements. How can introduction of bugs be avoided?
  • Can/should emission data be corrected after data logging?
  • How do we avoid losing data during software updates?
  • Can cloud-based DAHS systems be quality assured?
We will also investigate how internet connected DAHS systems can be implemented in high-risk power plants without risking data exposure and compromised control systems. Many DAHS systems are supported remotely by various vendors. Is it possible to make a hack-safe solution?
