Automatic Veriication of a Hydroelectric Power Plant 1

We analyze the speciication of a hydroelectric power plant by ENEL (the Italian Electric Company). Our goal is to show that for the speciication of the plant (its control system in particular) some given properties hold. We were provided with an informal speciication of the plant. From such informal speciication we wrote a formal speciication using the CCS/Meije process algebra formalism. We deened properties using-calculus. Automatic veriication was carried out using model checking. This was done by translating our process algebra deenitions (the model) and-calculus formulas into BDDs. In this paper we present the informal speciication of the plant, its formal speciication, some of the properties we veriied and experimental results.
