Description
Technical Field
The present invention relates to a power consumer ultra-capacity monitoring technology, and more particularly, to a power consumer ultra-capacity monitoring method, device and system.
Background
In power supply and use, the phenomenon of over capacity power utilization of users sometimes occurs. Particularly, the power price is segmented when the national power grid implements the peak, flat and valley time in recent years, and the phenomenon that large industrial users exceed the appointed capacity power utilization in the valley time period is obvious because the power price is lower in the valley time period. In the electric power marketing work, although the super-capacity power consumption of most industrial users is not large, the super-capacity power consumption still needs to be processed according to the flow because the super-capacity power consumption endangers the safe and stable operation of an electric power system, and thus inconvenience is brought to power supply enterprises and power consumption customers.
Aiming at the over-capacity power utilization behavior of power consumers, in the prior art, power grid enterprises mainly rely on a marketing inspection system for monitoring and analysis. The marketing inspection system monitors and inspects power supply emergency disposal, operation results, marketing work quality, abnormal phenomena in marketing service resources and inconsistent data generated by a marketing service application system through inspection theme management. For the phenomenon of the over-capacity electricity utilization of the user, the inspection system sets an alarm threshold value according to the electricity utilization capacity reported by the user, and when the monthly electricity utilization of the user exceeds the threshold value, the inspection system automatically generates an over-capacity record so as to generate an inspection work order for processing. However, when the existing inspection system is used for processing the problem of the super-capacity power utilization of users, the following disadvantages are mainly existed:
(1) the existing inspection system judges whether the user has the problem of super capacity electricity consumption by counting the monthly electricity consumption of the user, and the specific method comprises the following steps:
the theoretical maximum electricity consumption is the maximum operation capacity of the client in the month x the days of the calendar of the month (30 or 31) x the hours of the operation of the day (24);
the customer tolerance rate is (the customer monthly electricity consumption/the theoretical maximum electricity consumption-1) × 100%
The algorithm can reflect the measurement of the user's excess capacity power utilization, but cannot reflect the real-time power utilization power of the user, so that the power size of the user's excess capacity power utilization cannot be calculated.
(2) The existing inspection system cannot record the time length of the ultra-capacity power utilization of the user, so that the basis for processing the ultra-capacity user is insufficient.
(3) The existing inspection system does not fully consider the requirements of a user side, and cannot provide an alarm signal in real time when the power consumption of the user reaches the delay detection time. For a large number of unintended over-capacity users, the current system threshold setting is too low, which may cause trouble to the users.
(4) For severe over-capacity users, the existing inspection system is not provided with a corresponding load control device and can only rely on manual work to carry out on-site processing.
Aiming at the phenomenon of overload power utilization, an overload alarm problem processing technology appears in the prior art, and the principle is that whether the user power exceeds a rated value or not is judged by detecting the current under the premise that a voltage signal is considered to be unchanged. And when the detected current value exceeds a preset alarm value, outputting an alarm signal.
The overload alarm problem processing technology has the following defects:
(1) the technology only detects the current value and ignores the problem of voltage change. In actual power system operation, voltage can change according to system operation conditions, especially in the area that industrial electricity is concentrated, the load factor is higher, voltage change can be more obvious, if neglect this problem, will produce great influence to the testing result accuracy.
(2) The technology does not determine the time length of the overload operation of the user, and can not effectively distinguish whether the user is short-time normal overload or long-time overload power utilization.
(3) The technology does not consider that the power consumption of the user is recorded and uploaded to a power grid enterprise in real time, and strong evidence cannot be provided in actual power inspection.
(4) The technology has no system protection and load control functions. When the user is seriously over-capacity, the over-capacity load of the user cannot be effectively cut off, and potential safety hazards can be brought to the normal operation of a power grid.
