Aigües de Terrassa

			Description of the activity The water pumping station of “Aigües de Terrassa” develop the following functions: Treat and makes water apt for domestic, industrial, commercial and council use Pumps the treated water to the heigth of the main distribution tanks Supplies a population of, approximately, 240,000 inhabitants (Terrassa and surrounding towns) Objectives Control the efﬁciency of the plant and to follow up the processes. Speciﬁcally: To control the basic raw materials: Water (Extracted and Sent) Energy (Contracted power around 3.5 MW, 6 periods) To improve the safety of the water treatment process: Most accurate control in the addition of reactives: Redundant system Description of the application The developped application contemplates the following functions: Monitoring and registering of the water treatment and pumping processes: Flows, reactives control, concentration of chlorines, pipe pressure, monitoring of sludge treatment from ﬁltering Monitoring and register of the energy consumption of the plant: Total and partial consumption of energy Instant power of the plant and the main loads Ratio between the power and the ﬂ ow of the pumped clean water Displaying and control of the earth-leakage protection To make reports and statistics Water and energy demand tables and charts Alarms Results Operation cost control. Improve the ratio power/ﬂ ow to increase the efﬁ ciency of the pumps Study and Monitoring of all the production data, such as reactive consumptions, operating ratios, etc. Reduction in the cost of the energy by the follow up of: The energy consumption per each tariff, and pumping the maximum quantity of water in valley hours The cosφ of the installation Improvement in Maintenance: Detection of overloads in machines Veriﬁcation of the suitable ﬂ ow for each machine Veriﬁcation of the non-return valves Forecast of the preventive maintenance of the pumps after a certain number of worked hours Veriﬁcation of the electrical insulation List of the used materials CVM BD Power analyzers CBS-8 multipoint earth-leakage relays CVM R8-A Power analyzers LM-24-M pulse centraliser MRT sets of radio communication equipment + antennas TCP2RS ethernet converters Ampliﬁers RS-485/RS-485 Current transformers TC
