Foreword

GB/T 19115 "Wind and Light Complementary Power Generation System" is divided into the following two parts.

--- Part 1. Technical conditions;

--- Part 2. Test methods.

This part is the second part of GB/T 19115.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part replaces GB/T 19115.2-2003 "Off-grid household wind and solar hybrid power generation system Part 2. Test method", and Compared with GB/T 19115.2-2003, except for editorial changes, the main technical changes are as follows.

--- This section adds a test method for grid-connected wind-solar hybrid power generation systems (see Chapter 5);

--- Adjusted the scope of application (see Chapter 1);

--- Reference standard corresponding update (see Chapter 2);

--- Added test schematic and test method for grid-connected fan controller (see Figure 1, 6.3.1);

--- Added schematic diagram and test method for grid connection system test connection method (see Figure 5, 8.2);

--- Modified the schematic diagram of the wind turbine simulator (see Figure 3);

--- Modified the inverter test method (see 6.4);

---Modified the detection method of the battery (see 6.5);

--- Revised the comprehensive performance test record table of wind-solar hybrid power generation system (see Appendix A);

--- Removed the unloader test method (see.2003 edition 5.6).
