Coalbed gas meter

The use of coal-bed methane power generation is a new energy use and environmental protection projects. 2006, the state will be included in the development of coalbed methane in 11th Five-Year energy development plan, to 2010, plans for the use of coal-bed methane up to 3 billion cubic meters or more, coal-bed methane installed capacity of more than 1500MW.

The main process system of coal-bed gas power plants including coal-bed gas pressurization system, gas engine system, waste heat boiler system and turbine generator system, deaerator water supply system, water treatment system, water supply and heating system and cooling water system, substation 220kV. The main process adopts the combined cycle mode of a waste heat boiler and a steam turbine to generate electricity, and the power generation efficiency is increased to about 44%. Through comprehensive utilization, the energy efficiency of the power plant can reach about 80%.

Shanxi Jincheng Sihe Coal Mine 120MW coal seam gas power plant is the country through the CDM (Clean Development Mechanism, namely the "clean development mechanism") key projects set up the way, and by the Asian Development Bank loans to build the Asia largest coal-bed methane power generation demonstration power plant. Shanghai Automation Instrumentation Co., Ltd. as a subsidiary of Shanghai electric (SEC) environmental protection group, is responsible for providing the entire plant instrumentation and control system solutions and equipment integration.

The project is configured with 13 pairs of redundant DPU, the whole plant monitoring I/O signals a total of more than 7000 points. It has 1 engineers, 25 operator stations, 2 historical data servers and 6 communication interface servers. From the scale point of view, the number of DPU configuration, I/O number and the number of workstations are more than a set of 300MW coal-fired unit control system.

In addition to the DCS platform, my company has a complete set of equipment instrumentation, two meters, large screen systems and other equipment. The temperature meter of 124 sets, 106 sets of pressure and differential pressure transmitter, pressure gauge, flow meter of 88 sets, 39 sets, 8 sets of actuators and other auxiliary instrument 240 sets; 3 sets of large screen display, large screen display graphics manager 1.

As the instrument and control system of the large coal bed gas power generation demonstration plant, the successful implementation of the scheme has set up the model of the instrument and control system of large scale coal gas power plant. The program is a major breakthrough in our country in the field of automation control, will lead the national large-scale coal-bed methane power plant control and management technology unceasing development, the development of large-scale coal-bed methane power generation industry will play a huge role in promoting.

Engineering example:

Jincheng Shanxi Sihe Coal Mine 120MW coal gas power plant is the country through CDM (Clean Development Mechanism, that is, clean development mechanism) set up in Asia's largest coal-bed methane demonstration plant.

Since the company as a supplier of Shanghai electric environmental protection group, be responsible for providing the instrumentation and control system (control) solutions and equipment integration.

Control system configuration scale:

On the DPU:13.

IO points: 6800 points.

Operator station: 25 Taiwan.

Engineer station: 1 Taiwan.

Communication interface: 6 server.

For historical data server: 2

Matching instrument:

124 sets of temperature meter.

There are 106 sets of pressure and differential pressure transmitter

Table 88 sets of pressure.

39 sets of flow meter.

8 sets of actuators.

The other 240 sets of auxiliary instrument.

The successful implementation of the project has set up a model of the instrumentation and control system of large scale coal gas power plant, with the international advanced level. Is another major breakthrough in the field of automation control in China, which will play an important role in promoting the development of the industry
