Description

Apparatus and method of monitoring performance of SOFC system}

The present invention relates to an operation control apparatus for a solid oxide fuel cell system, and more particularly, to accurately test a fuel cell system, and to finally manage and monitor a grid-connected peripheral system for a solid oxide fuel cell (SOFC). Driving control system H / W platform technology.

With the recent economic growth, the demand for electricity in developing and developing countries is expected to surge, and OECD countries need to replace their facilities due to the aging of the existing grid. However, large-scale investment in transmission and distribution facilities is required for the construction of central power plants, so decentralization of power generation facilities is necessary. From this point of view, the medium and small capacity flat tube solid oxide fuel cell is expected to be used as a main power source for home or small-scale power generation facilities, and thus energy saving effect can be achieved by reducing transmission and distribution facilities and high efficiency power generation. In the future, the power system is expected to become a smart grid that enables the selective use of power by consumers, that is, households, through the bi-directional exchange of information between power suppliers and consumers. As one of small-scale power generation facilities to which smart grid technology can be applied, power generation technology using fuel cells is widely studied.

The fuel cell has a mechanism for directly converting chemical energy generated by oxidation of fuel into electrical energy. It is regarded as an eco-friendly technology because there is almost no emission of pollutants, and because it can use various fuels in addition to petroleum, it is a theme that is attracting attention as a problem of resource depletion and next-generation green energy.

In particular, solid oxide fuel cells are being researched in advanced countries for home use and automobile use. However, domestic technologies are still lower than other fuel cells, and localization of related parts is urgent.

Since it is water, there is little pollution and there is no moving part inside the system, so there is no noise. Unlike the polymer electrolyte fuel cell, the reaction can be accelerated without the use of expensive platinum catalysts, and there are a lot of materials that can be used as fuels, and the electrochemical reactions occurring inside the fuel cell system are exothermic reactions. Combined power generation is possible.

7 is a flowchart conceptually illustrating a method for monitoring performance of a solid oxide fuel cell system according to another aspect of the present invention.

In order to monitor the performance of the solid oxide fuel cell system, the operation mode of the normal operation mode and the check mode is determined (S70). In normal operation mode, the fuel cell peripheral is operated as usual, and the state of the fuel cell peripheral is monitored during operation. In the test mode, a test signal is applied to the fuel cell peripheral and the response signal is analyzed. According to the analysis result, it may be determined whether the fuel cell peripheral device is operating normally.

Hereinafter, the peripheral devices included in the solid oxide fuel cell system and subjected to performance monitoring will be described in detail.

Peripheral devices (BOPs) are devices for fuel and air supply, cooling, and exhaust, and the concept of heat and mass balance is particularly important in solid oxide fuel cell systems. The Air Process System, which is the target of performance monitoring, is a system that supplies air (oxygen) to react with hydrogen to the fuel cell stack. Air supply systems include air cleaners, air blowers and air compressors.

In addition, the thermal management system (Thermal Management System) to maintain the water balance required for the entire system, may include a water management system (Water Management System) for cooling. Water management systems may include radiators, water pumps, deionizers, and water tanks.

And, there is a fuel supply system (Fuel Process System) for supplying hydrogen as a fuel, the fuel supply system may include a hydrogen tank, a pressure regulator, and a hydrogen recycler.

When the operation mode is determined, a predetermined control pattern is determined according to the determined operation mode, and accordingly, a control signal for the fuel cell peripheral device is generated (S72). That is, the fuel cell peripheral device is controlled according to the determined control pattern.

As such, when the fuel cell peripheral device is controlled, operation data is collected and received from the operating fuel cell peripheral device (S73). Then, it is preferable that the control data of the fuel cell peripheral device is displayed so that the user can directly monitor (S74).

Finally, the performance of the solid oxide fuel cell system is monitored by comparing the received operation data with the control pattern (S75). At this time, for performance monitoring, specification data related to the normal operation of the fuel cell peripheral device is first received from the specification database. In addition, the operation data of the fuel cell peripheral device may be collected, and the collected operation data may be stored in a log file form to simulate the operation of the fuel cell peripheral device. Once the operational data is stored, the stored log files can be applied to model the solid oxide fuel cell system. In particular, in order to model the nonlinearity of the solid oxide fuel cell system, it is preferable to adopt the Wiener model as described above, and a parameter value such as Equation 1 may be used.

When the operation data and the specification data are received as described above, the specification data stored in the specification database is compared with the log file to detect whether an error occurs in the operation of the solid oxide fuel cell system. In addition, analyzing the log file can evaluate the performance of the solid oxide fuel cell system.

If it is determined that an error has occurred in the system while monitoring the performance of the system (S77), an error message is immediately output to the user (S78).

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, the appended claims are intended to cover such modifications or changes as fall within the scope of the invention.
