In this paper, a Conformance test platform is built for intelligent electronic devices (IEDs) from different manufacturers based on IEC 61850 communication protocol. A Conformance test of time delay of message transmission between two IEDs, made by the same or different manufacturers, is performed. The Conformance test platform, as well as the test results provide a helpful reference for IEC 61850 implementation.

Transparency is vital to realizing the promise of evidenced-based policymaking,where"evidence-based"means including information as to what data mean and why they should be trusted.Transparency,in turn,requires that enough of this information is provided.Loosely speaking then,transparency is achieved when sufficient documentation is provided.Sufficiency is situation specific,both for the provider and consumer of the documentation.These ideas are presented in two recent Us commissioned reports:The Promise of Evidence-Based Policymaking and Transparency in Statistical Information for the National Center for Science and Engineering Statistics and All Federal Statistical Agencies.Metadata are a more formalized kind of documentation,and in this paper,we provide and demonstrate necessary,sufficient,and general conditions for achieving transparency from the metadata perspective:conforming to a specification,providing quality metadata,and creating a usable interface to the metadata.These conditions are important for any metadata system,but here the specification is tied to our framework for metadata quality based on the situation-specific needs for transparency.These ideas are described,and their interrelationships are explored.

Formal methods for test sequence generation from FSM have been studied widely andthoroughly,but most real communication systems can only be modeled as EFSM exactly.Data portion in EFSM brings difficulties for test suite generation.In this paper,the strategyof generating test suite from protocols modelled as EFSM is presented.This strategy consid-ers testing of both the control portion and data portion of protocols.A software,the testsuite generation system(TSGS)based on above strategy,is introduced.

The digital substation system consists of an Intelligent Electronic Device (IED) which requires information for the supervision, protection, and control, as well as a client operating system for substation operation. IEC 61850 communication standard has been defined for information exchange between heterogeneous digital devices in such substations. Currently, the Korea Electric Power Corporation (KEPCO) digital substation system uses unbuffered reporting and Generic Object Oriented Substation Events (GOOSE) communication functions for monitoring, protection and control automation. However, it is expected that the Setting Group function will be needed to operate adaptive intelligent substation system. The Setting Group function is advantageous in that it is possible to change the setting of the IED in one unified way through the client operating system, rather than changing the correction value of an IED through different manufacturer-based engineering tools. In order to utilize the Setting Group function of the IED in real substation scenario, it is necessary to test both the communication function with the host operating device and the electric functional test to ensure that correction value is properly changed. In this paper, we introduce the IEC 61850 Setting Group function, and propose a method that can integrate communication function and electrical function test of an IED conforming to the setting group functionality. We also tested the Setting Group function of the actual IED device through the proposed integrated functional test method and analyzed the results. We were able to simplify the process of testing both the electrical and communication signals in digital substations.

Unwanted water production together with oil and gas production is a striking problem in oil and gas industries, and many approaches have been examined to overcome this major problem. Preformed particle gels (PPGs) showed dramatically good properties for this purpose in mature oil and gas reservoirs. In this study, we carefully synthesized an efficient series of PPGs with using a design of experiments (DOE) software. Acrylamide (AAm)/Acrylic acid (AA) mole ratio, N,N’-methylenebisacrylamide (MBA) mole percentage and swelling time were considered as key parameters to examine PPG swelling behavior. Our results presented a detailed empirical correlation, which could significantly predict the swelling capacity of PPGs in CaCl2 salt solution (200,000 ppm).
