Abstract: A thermoelectric power generation system includes a shell-and-tube heat exchanger configured such that a tube including double tubes of an inner tube and an outer tube is inserted into a shell, and a thermoelectric power generation module inserted into between the inner tube and the outer tube. The thermoelectric power generation module generates thermoelectric power using a temperature difference between a first medium flowing in the inner tube, such as coolant, and a second medium flowing outside the outer tube in the shell, such as excess water vapor.

Abstract: A thermoelectric power generation system 20 includes a heat exchanger 1 having double tubes which are an inner tube 1a and an outer tube 1b, and a thermoelectric power generation module 2 mounted between the inner tube and the outer tube. The thermoelectric power generation module generates thermoelectric power using a temperature difference between a medium inside the inner tube and a medium outside the outer tube, and a highly thermal conductive elastic sheet 3a, 3b is mounted between the thermoelectric power generation module and the inner tube and/or the outer tube in close contact therewith.

Abstract: A plug-and-play transformer station automation system automatically recognizing a setting at the time of installing an IED or an MU when a new system is constructed and the number of lines is increased, and a terminal automatic recognition method by that system are provided. A transformer station automation system 10 connects multiple protective control terminals 3-1 to 3-n with device terminals 4-1 to 4-n relaying a monitoring/controlling target device through a process bus 7, and connects a central monitor/control apparatus 1 with the protective control terminals 3-1 to 3-n through a station bus 6. The central monitor/control apparatus 1 has a function of checking a symbol and a letter string subjected to screen display extracted from a CID file with information in the SSD file to generate an SCD file.

Abstract: A network monitoring apparatus includes: a monitor unit monitoring data transmitted in a network monitoring and controlling an electric power system of a transformer substation; a system fault determination database representing a correspondence between a fault in the electric power system and a type of data transmitted in the network; a calculation unit calculating a data amount monitored by the monitor unit; a first determination unit determining whether or not the data amount is greater than a threshold value; a second determination unit determining, when the monitored transmission amount is greater than the threshold value, a presence/absence of an occurrence of system fault based on the system fault determination database and a type of the monitored data; and a stop control unit stopping, when the second determination unit determines that the system fault occurs, the determination carried out in the first determination unit.

Abstract: An SC includes a determination database storing determination data. The SC includes a specific-event-occurrence detection unit that detects an occurrence of a transformer substation specific event, a data-compression-instruction output unit, a specific-event-recovery detection unit that detects an end of the specific event, and a data-compression-termination-instruction output unit. An MU and an IED each include a data compression flag setting unit and a data compression unit. The data compression flag setting unit sets a data compression flag to be ON when the MU and the IED receive a data compression instruction, and sets the data compression flag to be OFF when the MU and the IED receive a data compression termination instruction.

Abstract: Provided is a monitoring and control system which, by displaying memo information created by an operator on an arbitrary system screen, can enhance freedom of memo display and fully exhibit the effectiveness of memo information. A memo data operation portion 4 receives an input of memo information from an input device 2, imparts attribute information relating to an arbitrary system screen to the memo information, and outputs this with the memo information to a client-side data management portion 6. A display device 1 displays the memo information on a system screen having attribute information.

Abstract: According to one embodiment, a server 11 performs aggregate signal processing for n-to-one signal transmission. The processing includes waiting processing and time adjusting processing. In the waiting processing, from a time point where a first constitutional element signal constituting a specific aggregate signal bound for the upper level control center reaches the server until a wait time that is based on a preset condition elapses, the server waits for another constitutional element signal of the specific aggregate signal to arrive (S202-S208). In the time adjusting processing, the server extracts an earliest generation time from generation times attached respectively to constitutional element signals arriving during the waiting processing, and attaches the extracted time as a generation time of the specific aggregate signal (S210).
