Embodiment 1

[0033] Embodiment 1: Define the state of the device and specify its operation steps to realize the control of each operation process

[0034] The device state is classified according to the device process, including at least initialization state, waiting state, start state, standby state, running state, normal shutdown state, and emergency shutdown state. The specified operation steps are executed in different states, and the difference between different device states state transitions are possible. The state transition can be performed according to user actions such as executing the action of starting the electric stack, or according to the measured value of the device such as the temperature is greater than a specified value, and the relevant transition operation steps are executed.

[0035] The initialization state is to detect whether the measured value of the device and its connection state are abnormal; the waiting state is to wait for user operation instructions and set...

Embodiment 2

[0047] Embodiment 2: Programmable Table Setting of Sequence Control Flow

[0048] The sequential control process of the fuel cell device, such as start-up and shutdown, and different device processes will result in different control quantities at different times. The control quantities include temperature and different gas supply quantities, which correspond to different instruments and equipment, and the adjustment is complicated. The programmable parameter table is used for setting, and the setting is uniform. The setting content includes the time period, temperature period, and different gas supply volumes. The gas supply types include methane, hydrogen, nitrogen, water and air. The corresponding table items when the gas is not used set to 0. Combination settings of parameters can be carried out, and operations such as creating, saving and loading the parameter table can be performed.

Embodiment 3

[0049] Embodiment 3: Programmable Table Setting of Fault Judgment Parameters During the operation of the fuel cell device, the types of faults and their fault definitions are different in different states, and different users are concerned about different faults. The programmable table is used to set the fault judgment parameters. Including that the user can add the fault item by himself, and the fault item is the measurement item parameter of the sensor, and can define its upper and lower limits by himself, and can set the fault judgment parameters of one or more states in the table at the same time.

Abstract

A solid oxide fuel cell control device and a control method belong to the technical field of fuel cell control. The control device is characterized by comprising a cell stack subsystem, a gas supply subsystem, a load subsystem, and an apparatus and instrument control subsystem. A control software is programmed by a host computer to define a device state and to specify operation steps, and thus the control of operation processes for independent power generation by the device is realized. On-line modification of control parameters, fault determination parameters and system parameters can be carried out. The control parameters comprise programmable parameter table setting for starting a closing process in automatic control, temperature control target and adjusting amount setting for a normal operation process, and gas supplying amount setting in manual control; the fault determination parameters adopt programmable table setting; the system parameters comprise instrument communication parameter setting. Data monitoring and storage backup of specific positions of the device can be carried out, and the running state and fault information of the device can be displayed. Compared with the prior art, the device of the invention has the characteristics of simple structure, safety, reliability, and strong generality.

Description

technical field [0001] A solid oxide fuel cell control device and a control method belong to the technical field of fuel cell control, in particular to the technical field of solid oxide fuel cell control capable of independent power generation. Background technique [0002] Solid oxide fuel cell is a power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy at medium and high temperatures. It has wide fuel adaptability, high energy conversion efficiency, all solid state, modular assembly and zero It can directly use various hydrocarbon fuels such as hydrogen, carbon monoxide, natural gas, liquefied petroleum gas, coal gas and biomass gas.
