“…in contrast to similar solutions discussed in papers [1,2,10,11], the authors propose to use the correlation analysis not only with regards to flow rate signals, but also to pressure signals [14,15]. using pressure signals is aimed at reducing the time required to detect a leak.…”

“…the last solutions can be found in papers [1,2,10,11]. in the paper [1] the comparison of the two advanced algorithms can be found. an algorithm configured on the above schema as a slda combination, "due to its good performance and good reliability is more appropriated to be implemented in industrial controllers", than the second one, which is far more computationally sophisticated.…”

“…an example of this method is the inverse analysis method [9,19] and also so called methods with automatic control approach [1,2,10,11,16,18]. without doubt, the main advantage of both groups of methods is the ability to detect leaks in steady states as well as in transition states, resulting from a change in pipeline's operational conditions such as: an operating point change, valve's aperture and closure, pump's start-up or stoppage.…”

“…a common solution is an implementation of state observers, which estimate process variables, for example, the flow rate at pipeline's inlet and outlet [1,2,10,11] or other parameters to describe the flow e.g. the friction coefficient [2,10,11].…”

(*) tekst artykułu w polskiej wersji językowej dostępny w elektronicznym wydaniu kwartalnika na stronie www.ein.org.pl Introductionliquid transmission pipelines may suffer from damages, which might result in leakages. therefore, leak detection system (lds) is an indispensable equipment of a pipeline installation. the main purpose of such system is to detect, locate, as well as determine the magnitude of occurred leak.Most popular lds are developed with the use of diagnostic methods, which are based on measurements of internal flow parameters, i.e. flow rate, pressure and fluid temperature. in the literature such methods are called internal (analytical, indirect) methods [2,11,17].the implementation of leak diagnosis process is a rather complex issue. the existing internal methods, whose review might be found in the papers [4, 10,11,17,19], on their own are not able to fulfill all mentioned above diagnostic tasks. their utility is limited to certain, defined operational pipeline's states and leaks' characteristics. thus, elaboration of effective and reliable lds requires applying of at least several internal methods working concurrently [17].taking into account that a lds should first detect a leak, internal methods, which are responsible for this diagnostic task, acquire particular significance. in practice, one or several methods must be used to increase the reliability of lds, which is defined as a degree of pipeline's operators confidence, i.e. absence of false alarms and also system's ability to detect any kind of occurred leak.the most advanced solutions, aimed at leakage detection, are based on process dynamics models. an example of this method is the inverse analysis method [9,19] and also so called methods with automatic control approach [1,2, 10,11,16,18]. without doubt, the main advantage of both groups of methods is the ability to detect leaks in steady states as well as in transition states, resulting from a change in pipeline's operational conditions such as: an operating point change, valve's aperture and closure, pump's start-up or stoppage.
