Heating transferring station applied in central heating supply
system, the system is difficult to generate and control the system
as a result of the large thermal lag, clear lag, and great
interference of temperature and weather elements. Aiming at above
conditions, the computer monitoring management system is effective
to implement central monitoring. The monitoring center computer
comprehensively analyzes the heat supply water and heat working
condition through the necessary data tested by field equipment and
issues instructions to monitoring points, coordinating the steady
reliable running. Aiming at heating transferring station heat
supply system, the central heating supply & heating
transferring station computer control system is a special control
system passed the acceptance inspection of Shandong Science
Commission, widely applied in many heating transferring stations,
achieving remarkable economic and social benefits.
System Features: According to the temperature, the advanced control
technology system adopts optimization control algorithm,
automatically generates the aperture of steam valve, and makes the
inlet and exit temperature reaching index value so as to realize
satisfying different weather requirements, energy saving and
consumption reducing. Due to the slow generation speed of typical
large lag ring control, the heat supply system adopts large lag
control algorithm and makes feed-forward compensation by leading
water complement flow, improving control speed and steadiness.
Besides, according to the backwater pressure, the system
automatically changes the output frequency and voltage of frequency
converters so as to continuously generate water complement flow and
satisfy the pressure trace set value.
The system utilizing fuzzy self-adaptive control method realizes
optimum control. In a good production condition, the system
automatically inputs the major parameter in computer through press
keys, and gradually establishes optimum three-D matching, reaching
the best production condition. It is easy to solve the running
dislocation of heat network and realize balance running, greatly
improving the heat supply effect. Production condition analysis
system is functioned by recording historical curve and alarm,
available to find the fault point in the shortest time, easy to
analyze the influence of technique condition on working condition
and the accident causes.
With strong capacity of resisting disturbance, adopting
optoelectronic isolation technology at the signal input terminal
and digital filtering technology after A/D transition effectively
solves the resisting disturbance problems and intensifies the
steadiness.
The central management function system is capable of collecting
real-time data. The system can realize cost accounting, heat
network optimization dispatch, and user charge management, and
access to ERP management according to the user’s needs.
