Product Introduction

Project Name: Star Power 110kV substation reactive power compensation device energy saving transformation project
Model:MSVC-10-4800kvar(4800MCR+4800FC) Quantity:3 sets  
MSVC-10-4000kvar (4000MCR+4000FC) Qty: 4 sets
MSVC-10-3300kvar (4000MCR+4000FC) Qty: 1 set
Project unit: Sichuan Star Power Co.
Project background and program:
Star Power is located in Suining City, Sichuan Province, and its power grid (hereinafter referred to as "Star Grid") is mainly responsible for the power supply of Funshan District and Anju District in Suining City, with a power supply area of more than 1900 square kilometers. The project selects the reactive power compensation problems of four 110kV substations in the Star Grid (mainly including Suibei, Suidong, Suinan and Anju) and carries out the construction and renovation in the stations.
The project is a remodeling for the problem of insufficient compensation capacity of the 4 substations in the Star Grid, and its main purposes are:
1. Ensure that the compensation capacity meets the design needs and the safety and stability of system operation.
2. Realize continuous linear adjustment of reactive power compensation capacity and optimal compensation through MSVC transformation.
3、MSVC reduces labor intensity and improves work efficiency.
According to the information provided by Star Power and on-site investigation, the current problems of Star Grid substations (Anju, Suidong, Suibei, Suinan) are:
1, part of the substation compensation capacity is insufficient, such as Suidong station, failed to meet the requirements, need to increase to ensure the safety and stability of system operation.
2, substation reactive power compensation for manual casting, subject to human factors constraints, can not do timely casting and fast response, the response of the casting switch used is also slow.
3、The reactive power compensation capacity of the substation is fixed, and the number of groups is small, so there is over-compensation or under-compensation in the casting and cutting, and the scientific optimal compensation cannot be realized.
The existence of the above problems affects the safety and reliability of power supply to the Star Grid, and causes hidden danger to the operation of the grid, which is not conducive to its operation and system stability. In order to ensure the safety and reliability of power supply to the Star Grid, and to reduce the level of line loss of the grid under the jurisdiction of the Star Grid, in view of the above problems of the existing four 110kV substations, the MCR-type equipment is used for the reconstruction of the Star Grid, which can solve the above problems, and realize the dynamic, accurate, and timely reactive power compensation, timely reactive power compensation.
Operation effect: After putting the equipment into operation, it fully meets the demand of users, and the equipment quickly follows the change of load to ensure that the real-time power factor is more than 0.98, stabilizes the voltage of the grid, and ensures the safety and reliability of power supply to the grid.
