Abstract

The invention provides a system for generating hydrogen through a high-temperature solid electrolytic tank by means of thermal power plant peak load regulation electricity. The system for generating the hydrogen through the high-temperature solid electrolytic tank by means of the thermal power plant peak load regulation electricity comprises a power grid peak load regulation control system, a power transmission and distribution and electrolytic tank power supply system, a high-temperature solid electrolytic tank hydrogen generating system, an electrolytic tank high-temperature steam supplying system and a hydrogen collecting, purifying and outward transmission system. The power transmission and distribution and electrolytic tank power supply system is a newly added interval on an outgoing bus of a power plant. An electric switch is arranged on the interval. The electric switch is connected with a step-down transformer and an inverter on a power transmission network. The other end of the step-down transformer and the other end of the inverter are connected with the high-temperature solid electrolytic tank hydrogen generating system. In the electrolytic tank high-temperature steam supplying system, a power plant main steam bypass guides out high-temperature steam, and the high-temperature steam is supplied to the electrolytic tank. By the adoption of the system for generating the hydrogen through the high-temperature solid electrolytic tank by means of the thermal power plant peak load regulation electricity, electrolysis hydrogen generation is conducted through the thermal power plant peak load regulation electricity, the main steam of the power plant is guided out, electrically overheated and then conveyed into the electrolytic tank, the hydrogen generation efficiency of the solid electrolytic tank is improved, the peak load regulation electricity of the power plant is greatly utilized, and a valuable peak load regulation load is provided for the power plant.

Description

technical field [0001] The invention relates to the fields of hydrogen production and power peak regulation, in particular to the fields of electrolytic hydrogen production and flexible peak regulation of thermal power plants. Background technique [0002] In recent years, in China's three northern regions, the power market has ample capacity, gas turbines, pumped storage and other peak-adjustable power sources are scarce, and the contradiction between power grid peak-shaving and the flexibility of thermal power units is prominent, and the grid accommodates new energy sources such as wind power, photovoltaic power, and nuclear power. Insufficient capacity, wind abandonment phenomenon is serious. The combined heat and power units operate in the mode of "heating and power generation", and the peak regulation capacity is only about 10%. Difficulty in peak regulation has become the most prominent problem in power grid operation. At present, domestic thermal power flexible peak...
