[0049] Figure 1 This is a flow chart of a method for comprehensive evaluation of electric power facility construction planning provided by the present invention. This embodiment is applicable to situations where different electric power facilities support different communication protocols, which is not convenient for unified management of electric power facilities and easily brings inconvenience to later operation and maintenance management. The method can be executed by a comprehensive evaluation device for electric power facility construction planning provided by an embodiment of the present invention. The device can be implemented by software and / or hardware, and is usually configured in an electronic device, such as Figure 1 As shown in Figure 1, the comprehensive evaluation method for power facility construction planning includes the following steps:

[0050] S101. Associate the equipment in the electric power facility construction plan with the communication protocols used by the equipment to obtain a communication equipment reference table.

[0051] In the embodiments of the present invention, the equipment (power equipment) includes but is not limited to smart meters, Hall current sensors, Hall voltage sensors, substation automation systems, distribution automation systems, energy management systems and communication network equipment. As a communication analysis, taking smart meters as an example, smart meters (such as DTSD1352-C model electric energy meters) communicate with the main station through the DL / T 645 protocol to realize functions such as remote meter reading. Depending on the model of the smart meter, the smart meter can also communicate remotely through the MODBUS protocol, DLMS / COSEM protocol, IEC 61850 protocol, Zigbee protocol, and LoRaWAN protocol.

[0052] To achieve a refined analysis of the power facility construction plan, the equipment in the power facility construction plan is associated with the communication protocols applied by the equipment to obtain a communication equipment reference table. In addition, the power equipment in the power facility construction plan is classified according to functions.

[0053] S102. For each communication protocol, determine the communication area of all the equipment applying the communication protocol from the power grid planning floor plan.

[0054] In an embodiment of the present invention, for each communication protocol, determine the communication area of all the equipment applying the communication protocol from the power grid planning floor plan, and the communication area may be the smallest area covering all the equipment applying the communication protocol.

[0055] Exemplarily, in an embodiment of the present invention, the minimum circle covering method is used to calculate the minimum circle covering all the equipment applying the communication protocol in the power grid planning floor plan as the communication area. The minimum circle covering is an algorithm problem in mathematics, which studies how to find the minimum circle that can cover a group of points on a plane.

[0056] Exemplarily, taking the incremental method in the minimum circle covering method as an example, all the equipment applying the communication protocol is regarded as points in the power grid planning floor plan, and the specific algorithm is as follows:

[0057] 1. Randomly arrange all the points.

[0058] 2. Initially, randomly find two points, denoted as P1 and P2, and obtain an initial circle with P1P2 as the diameter, denoted as C2 (Ci represents the minimum circle containing the first i points).

[0059] 3. Add points in sequence. Let the current point be Pi. If Pi is inside the current circle Ci-1, then Ci = Ci-1 (indicating that the minimum circle has been found); otherwise, go to step 4.

[0060] 4. Construct a new circle Ci with P1Pi as the diameter.

[0061] 5. Find a point Pj (j < i) that is not in Ci, and construct a new circle Cj with PiPj as the diameter.

[0062] 6. Find a point Pk (k < j < i) that is not in Cj. Then Pi, Pj, and Pk must be on the boundary of an updated circle. Now we can determine that there are three points (Pi, Pj, Pk) on the boundary of an updated circle. Since three points determine a circle, Pi, Pj, and Pk form a new circle, which must be able to cover the first i points. In this way, loop until the minimum circle covering all the points is found.

[0063] S103. Determine the equipment that does not apply the communication protocol within the communication area as the equipment to be replaced.

[0064] In the embodiment of the present invention, after determining the smallest circle covering all devices applying the communication protocol as the communication area, devices in the communication area that do not apply the communication protocol are determined as devices to be replaced.

[0065] S104. Search the power facility construction plan for equipment that has the same functions as the equipment to be replaced and uses the same communication protocol as the equipment to be replaced as replaceable equipment.

[0066] In an embodiment of the present invention, a device having the same function as the device to be replaced and applying the communication protocol is searched for as a replaceable device in the power facility construction plan, and the device to be replaced is replaced with the replaceable device. In this way, the communication protocol in the power transmission system is unified, which facilitates the unified management of power facilities and improves the convenience of subsequent operation and maintenance management.

[0067] Illustratively, in some embodiments of the present invention, according to the equipment function classification in the aforementioned embodiments, equipment with the same function as the equipment to be replaced and applying the communication protocol is searched from the power facility construction plan as a backup replacement equipment, and the reliability index of the equipment to be replaced is used as a reference index. The reliability index of the backup replacement equipment is compared with the reference index, and the backup replacement equipment with a reliability index greater than the reference index is selected as the replaceable equipment, thereby ensuring the allowable reliability of the replaced equipment.

[0068] After determining the devices in the communication area that do not apply the communication protocol as the devices to be replaced, the cables that are separately connected to the devices to be replaced are determined as the control samples to be replaced.

[0069] S105. Calculate the comprehensive cost of the power facility construction plan after replacing the equipment to be replaced with replaceable equipment.

[0070] In an embodiment of the present invention, the comprehensive cost of the power facility construction plan after replacing the equipment to be replaced with the replaceable equipment is calculated. Exemplarily, the comprehensive cost of the power facility construction plan includes multiple components, such as the material cost, transportation cost, installation cost, and accessory cost of the equipment, and the material cost, installation cost, and accessory cost of the cable, which are not limited in this embodiment of the present invention.

[0071] For example, in some embodiments of the present invention, the comprehensive cost of power facility construction planning also includes the wiring cost generated by replacing the control sample to be replaced with the control sample of the replaceable equipment. The calculation formula of the wiring cost is:

[0072]

[0073] Z2=A+B+C;

[0074] Z3=N1G I +N2G2+…+Nn G n ;

[0075] Z = Z1 + Z2 + Z3;

[0077] In some embodiments of the present invention, after calculating the comprehensive cost of the power facility construction plan after replacing the equipment to be replaced with replaceable equipment, the comprehensive costs of the power facility construction plans are ranked to obtain a cost ranking, and the cost ranking is gradient-divided to determine the gradient value of the comprehensive cost of each power facility construction plan as an evaluation of the power facility construction plan.

[0078] The comprehensive evaluation method for electric power facility construction planning provided by the present invention associates the equipment in the electric power facility construction planning document with the communication protocol applied by the equipment to obtain a reference table of communication equipment. For each communication protocol, the communication area of ​​all equipment applying the communication protocol is determined from the power grid planning plan, and the equipment in the communication area that does not apply the communication protocol is determined as the equipment to be replaced. Equipment with the same function as the equipment to be replaced and applying the communication protocol is searched from the electric power facility construction planning document as replaceable equipment, and the comprehensive cost of the electric power facility construction planning after replacing the equipment to be replaced with the replaceable equipment is calculated. By replacing the equipment to be replaced with different communication protocols with replaceable equipment with the same communication protocol and the same function, the communication protocol in the transmission system is unified, which is convenient for the unified management of electric power facilities and improves the convenience of later operation and maintenance management.
